->"''54. Do you not realize how much gold actually weighs?''"
-->-- ''[[http://www.rinkworks.com/fnovel/ The Fantasy Novelist's Exam]]''

Writers frequently misapply, distort, or outright forget about the concept of density and its implications. This results in such oddities as most metals, including gold, being treated as weighing the same as an equivalent volume of iron or steel, with the possible exceptions of aluminum (famous for weighing less) and lead (famous for weighing a lot). The only thing typically treated as denser than lead is matter from a neutron star, by orders of magnitude -- there's apparently nothing in between.

By the same token, anyone can lift as much of a "light" object, such as feathers, Styrofoam, or in the worst cases even ''stacked flat paper'', as can be made practical to carry.

What's worse, even if the writers get it right, sometimes the actors won't, due to not compensating for the difference between the weight of the prop and the weight of the object it's supposed to represent through acting.

Generally, the only exception to "people carrying around big gold ingots with ease" comes when the density of gold relative to other substances is itself a major plot point. Especially since gold is actually 70% more dense than lead.

Sometimes an AcceptableBreakFromReality, sometimes not. It helps to be in a fantasy setting, and [[MagicAIsMagicA consistency is key]]. Keep in mind that sometimes reality can make something incredibly boring. (One of the most common house rules for most tabletop games is that gold is weightless). {{Balloonacy}} is a subtrope dealing with wild over- and under-estimations of the lifting capacity of Helium, Hydrogen or hot air. SoftWater follows this trope, and BriefcaseFullOfMoney is closely related.

!!Examples:

[[foldercontrol]]

[[folder:{{Anime}} and {{Manga}}]]
* Skipper from ''Manga/TheDaughterOfTwentyFaces'' must be one heck of a strong guy, since he manages to transport not one but ''two'' large cases of gold. The fact that he does it underwater only ''adds'' to the difficulty, since he has to wear a clumsy diving suit. Especially since gold weighs about 19 times as much as water, and the buoyant forces would make it weigh about 18 times as much.
* In ''Manga/DetectiveConan'' one episode has golden bricks which were covered in moss to make them look like old stone bricks, and the titular character easily lifted as if it were that light.
* ''FuturePoliceUrashiman'' episode 22. Ryu, in an invasion of Necrime's fortress, fills his shirt with gold bars, which he has no trouble picking up. He's weighed down, but he can still walk and he can pick the bars up with one hand.
* ''Franchise/{{Gundam}}'' is a ''chaotic'' offender, using various types of fantastic metals to build the mechas.
** ''Anime/MobileSuitGundam00'' had it slightly realistic as the one made from average metal weighed up to 134 tons and [[MightyGlacier a walking brick]] to boot, these that are far lighter (around 60-70 tons) are stated to be made from E-carbon, a super strong material that used in the construction of Space Elevator (theoretically, TruthInTelevision) and yet, they're [[NoodlePeople slender]], [[FragileSpeedster far from invincible and prefer to dodge instead]].
** In ''Anime/MobileSuitGundamSEED'' and sequel (''[[Anime/MobileSuitGundamSEEDDestiny Gundam SEED Destiny]]''), TheKingdom (Orb) has their MechaMooks (Astray & Murasame) far lighter than TheFederation (OMNI) and TheAlliance (ZAFT), and in a way of LampshadeHanging/ HandWave, is made of [[IncrediblyLamePun Foaming]] [[AppliedPhlebotinum Metal]].
** ''Anime/MobileSuitGundam'', by the advancement of technology, Mobile Weapons constantly decreased in gross weight (and to a lesser extent, size) while retaining same or more firepower yet much faster than the original.
** ''Anime/MobileSuitGundamWing'' builds the titular Gundams from...well, [[{{Unobtainium}} Gundanium Alloy]], that would be a HandWave for them having 7-8 ton. Meanwhile, 7.0 tons LEO are made from titanium alloy.
* Averted for gold in ''Manga/{{Naruto}}'' when the Fourth Kazekage has the power to control gold, because gold is realistically heavy and malleable in this series. Instead of using it offensively, he uses these properties of gold to interfere with his foes' physical attacks, making them heavier.
* In ''Anime/NeonGenesisEvangelion'', LCL has the density of water if someone is blowing bubbles in it, but has the density of air if someone is crying in it. The ways of the [[spoiler: blood of an EldritchAbomination]] are mysterious indeed.
* In ''Anime/NinjaScroll'', hordes of {{Ninja}}s are seen doing full-on {{Ninja Run}}s ''uphill'' (well, up inclined planks) onto ships, while carrying chests filled with gold, which are ''balanced on one shoulder''. Those are some damn strong Ninjas.
* ''Manga/OnePiece'' is not known for its realistic physics, but during the Skypeia Arc a group of average, non-powered townspeople collectively carried a chunk of gold the size of an apartment complex (and thus many, many times their collective size) with little difficulty, and were even able to ''run'' while carrying said gold. Of course, utterly ridiculous feats of strength are ''very'' common in the series.
* ''Anime/SamuraiChamploo'' ep. 13 opens with a group of pirates making a raid, at one point they effortlessly throw suitcases full of gold from ship to ship.
* In ''VisualNovel/UminekoNoNakuKoroNi'' episode 11, Rose puts a brick-sized gold bar into the bag of her nine-year old daughter Maria, who doesn't react even slightly to the weight that must be close to 60 pounds! However, just a bit later Rosa uses the same bag as a blunt weapon with extreme effectiveness -- consistency was just too much trouble, apparently. In the Visual Novel, the ingot is given an approximate weight of, I believe, around 11 kilograms; in addition, it's directly stated that what she carries is in a blanket which she later use as a weapon against the [[spoiler: goatmen attacking her and Maria]]
* In ''Anime/TheFumaConspiracy'', Fujiko successfully smuggles a large shingle made of gold under her jacket and moves very quickly and agilely despite the presumed large weight.
[[/folder]]

[[folder:Comic Books]]
* ''ComicBook/WelcomeToTranquility'': Minxy builds a plane out of solid gold, and it is specifically mentioned that it will not fly because it is too soft and dense a metal. [[RuleOfCool It does anyway.]]
* ''ComicBook/XMen'': Piotr Rasputin has an official weight of 114 kg, and a height of 198 cm. When transforming into his [[ChromeChampion metal form]], his height becomes 226 cm, while his weight doubles to 228 kg. Assuming these numbers are correct, refers to him turning into metal instead of just gaining a metal coating, his human density is roughly equal to 1 kg/l, his metal form would have a density of 1.35 kg/l, or about half the density of aluminium. The kicker? The metal he transforms into is explicitly compared to osmium, the element with the highest density (22.6 kg/l, or exactly twice as dense as lead). If his metal form actually was osmium, Colossus would weight 3826 kg.
* The titular superhero of ''ComicBook/TheVision'' has the power to "control his density". This power is used often to become intangible, super-hard, and ''heavy.'' Changing density doesn't affect his volume, either. Presumably, the mass needed to increase or decrease his density comes/goes to another dimension.
* Mass Master from ''ComicBook/PowerPack'' has the power to change his density, which ''also'' changes his volume. His mass remains the same. Becoming denser shrinks the Mass Master, and becoming less dense makes him a cloud larger than his original body.
* Doll Man, in DC's relaunched Doll Man and Phantom Lady miniseries, became tiny, because his density was increased, while keeping his mass the same - thus making the fact that he can throw punches that full sized people can actually feel plausible. Awesome, makes perfect sense. They also have scenes of Phantom Lady holding him in her hand, or on her shoulder. So the issue of his mass is ignored during those instances.
* The story ''ComicBook/{{Asterix}} and the Cauldron'', Asterix is given charge of a small cauldron that is filled to the brim with silver coins. Given the density of silver, the cauldron should weigh more than Asterix does. Despite that, he is able to carry the full cauldron without the aid of the magic potion.
* In a ''ComicBook/SecretWarsII'' tie-in issue of ''Power Man and Iron Fist'' the Beyonder turns a skyscraper (made of steel, concrete, glass, etc) into solid gold (slightly denser than steel, much denser than the rest); it immediately collapses in on itself from the weight.
* Averted in a scene in ''ComicBook/SpirouAndFantasio: The Pirates of Silence''. A massive robbery is taking place in a secluded, off-the-radar city exclusively for VIP retreats. One robber is trying to lift a stack of gold bars, and ended up dropping most of them, not knowing how much gold weighs.
[[/folder]]

[[folder:Commercials]]
* In a case where density is exaggerated rather than underestimated, the Geico gecko accidentally steps in the cement for a starlette's new Hollywood Walk-of-Fame paving square. He leaves deep tracks in the wet cement, even though such a tiny reptile shouldn't even weigh enough to dimple the surface.
* In [[https://www.youtube.com/watch?v=rkB9OT2XVvA this DirectTV commercial]]. The women are about 10 times stronger than the Russian guy, based on their ability to lift the gold.
[[/folder]]

[[folder:Film]]
* ''Film/TheItalianJob1969'' features several Mini Coopers that are packed full with gold bars, but it doesn't affect their manoeuvrability or speed as they zip around Italy. Charlie [[LampshadeHanging does question]] whether the Minis will be able to take the weight of the gold, suggesting that the writers were aware of the problem.
* ''Film/TheItalianJob2003'' packs the Coopers with gold, and it uses a HandWave by stating that they've beefed up the shocks to accommodate the extra weight, though this is unlikely to be sufficient in real life. This film also averts the trope by using it as a plot point to assist the robbers in identifying which truck is carrying the gold based on how low it's sitting.
* In ''Film/DieHardWithAVengeance'', [[spoiler:the trucks loaded with looted gold bullion would not have been able to drive uphill]]. The producers admitted to just ignoring the issue. [[spoiler: The trucks wouldn't have been able to drive at all. In 1995, 150 billion dollars worth of gold should have weighed around over 9,000 tons. 13 trucks? 130 would have had trouble carrying that load.]] One thief ''tosses'' a gold bar to another thief. The way it hits him when he catches it, it should've ruptured a few organs. On the other hand, Zeus is ''very'' surprised at how heavy a single gold brick is.
* In ''Film/{{Goldfinger}}'', James Bond releases himself from a handcuff by using two gold bars as makeshift hammers. He later throws a bar through a respectable distance, hitting [[TheDragon Oddjob]] with it, but not doing any damage since the henchman is MadeOfIron. However, the film has a ActionFilmQuietDramaScene where Bond explains to Goldfinger how robbing Fort Knox, even if he killed all the troops stationed there, is impossible. Since gold is so heavy, the $15 billion worth at the fort, when added up, would weigh over 10,500 tons. Goldfinger would need at least sixty men, 200 trucks and twelve days to effectively load and take it all, while the US military will likely discover and move to stop the robbery within 2 hours of the first attack. From that, he concludes that Goldfinger's real plan is to use a "dirty" nuclear bomb to irradiate the gold, making it unusable for decades and thus making his own gold much more valuable.
* ''Film/TheMummyTrilogy'':
** The first movie has the ''Book of the Dead'' made of solid gold, yet characters are carrying it around as easily as a normal book that size.
** The sequel has a bracelet of the same material. Which is carried ''by a child'' most of the picture. Early in the film, when lugging around the bracelet in a box, he comments it weighs a lot.
** The sequel also has Johnathon lifting the Diamond of Ahm Shere, probably about a cubic foot in volume. That's a big rock, and Johnathan's no muscle man, but it's not completely impossible. Just unlikely.
* Averted in ''Franchise/SherlockHolmes in New York''. Holmes quickly realises that emptying the large underground vault of gold via the tunnel that has apparently been dug to it would be impossible in the time available, and that the whole vault is actually a fake built ''on top'' of the real one, with the access elevator rigged to stop at the new level, rather than the bottom of the shaft. The gold is meanwhile being removed at a more practical rate.
* Averted in ''Film/ThreeKings'' where one of the characters picks up a suitcase full of gold, and it promptly rips apart. They eventually are able to move the gold by transporting them in duffel bags with only a few bars in them. Unfortunately the actors still handle them like they didn't weigh more than ordinary bricks, while they held the bars in their hands.
* The 1950s sci-fi film ''Film/AtomicSubmarine'' features the title boat dodging ice falling off the bottom of the Arctic icecap. Ice floats because it is less dense than liquid water.
* Ice sinks in ''Serues/VoyageToTheBottomOfTheSea''. Ice floats because it is less dense than liquid water.
* ''Film/GIJoeTheRiseofCobra'' features an underwater ice-fall in the finale, though the ice was filled with metal, so possibly more likely. Ice floats because it is less dense than liquid water.
* ''Film/KingKongVsGodzilla''. At the beginning of the movie, a submarine traveling underwater passes by the iceberg Godzilla was trapped in at the end of ''Godzilla's Counterattack'' and chunks of ice begin breaking off as Godzilla starts to stir. Said ice chunks drop like stones around the submarine on a beeline to the seabed. Ice floats because it is less dense than liquid water.
* In the animated film of ''WestenAnimation/TheWaterBabies'', the heroes bombard an evil shark's castle by dropping giant snowballs and icicles from the iceberg floating above it. Granted, this ''is'' in a film where sea creatures speak, swordfish wear feathered hats, and ABoyAndHisDog breathe water. But still, ice floats because it is less dense than liquid water.
* In ''Film/InOldCaliente'' a payroll wagon loaded with gold coins kept getting held up by bandits on horseback, so the teamsters decided to melt down the gold into a heap of slag too large to move on horseback. When they were forced to retreat after being waylaid again, they lit the wagon on fire, rendering the gold immovable before the authorities could arrive. (In reality, the melting point of gold is 1,948 degrees Fahrenheit, so the teamsters never had the slightest chance of melting the coins unless they had thought to bring a blacksmith's forge with them.)
* In ''Film/TheDarkKnight'', the bank robbers toss duffel bags stuffed full of stacked money into the bus like they were bags of balloons.
* ''Film/TheLongShips'': A blatant example shows up in this 60's Viking movie. In it, the MacGuffin is a solid gold bell large enough to be mistaken for the roof of a small chapel. It is easily towed behind the Vikings' boat. No raft, no pontoons, just a solid gold bell floating effortlessly behind an oar-driven ship. Calculating the displacement, however, it might actually be possible if the bell had the right measurements and thickness.
* The movie ''Film/NightAtTheMuseum'' has one of the characters (a ten year old boy) effortlessly carry and run with a solid gold tablet. He should not have been able to even pick it up. It's even worse in the sequel, with the characters waving the supposedly solid gold tablet around as if it were a clipboard.
* ''Film/IronMan1'':
** Despite recovering from recent open-heart surgery, Tony Stark carries a lead-acid car battery like it's an empty cardboard box while in the terrorist camp. A car battery weighs about 30-60 pounds, however, so it's not impossible for the ripped Stark to be able to carry it, especially since his life literally depends on it. The density of the Iron Man suit itself seems to be really variable. At one point, Tony falls ''through'' concrete and destroys a car. Later, he gets thrown onto a glass roof... with no effect.
** Notably though, that 'glass' roof was over a nuclear reactor, and from the distance his arm hung into it after the glass broke, it was probably somewhere around half a foot thick, so it could very well have been able to support more weight than a drywall and 2x4 roof. Plus he fell further onto the house than the glass, in an earlier (more than likely more dense steel instead of the titanium-gold alloy) armor. And breaking even just an inch of perfectly normal glass, such as that in a computer monitor, takes a lot more effort than punching through drywall. The only reason glass breaks so easily normally is because it is normally very thin, less than a quarter inch, like the lenses in his helmet that did crack when Obadiah crushed it.
* In ''Film/{{Heat}}'', the bank robbers have to run from the police while carrying big duffel bags that are absolutely packed with paper currency. A full duffle would be able to hold enough stacked and bundled bills to weigh between 150 and 200 pounds.
* In ''Film/TheHiddenFortress'', a point is made about how heavy gold is, and the characters are staggering under the weight. But based on the volumes of their packs, they should be carrying between two and three tons of the stuff each.
* In ''Film/TheLordOfTheRings'' Gollum falls into a river of lava and sinks in it as if it's barely thicker than water. It may be molten, but it's still ''rock.'' The director has said that they know that shot is all wrong in terms of science, but decided to just let the RuleOfCool reign. Not to mention that letting the audience see Gollum being incinerated and cooked on top of the lava would probably be too gruesome for the film. RealityIsUnrealistic probably also applies since many viewers probably think [[SoftWater liquid is liquid]].
* In ''Film/IndependenceDay'', the aliens' hemispherical mothership is described as being over 550 kilometers in diameter and "In terms of mass, it's a quarter the size of the moon." This would give it an ''average'' density about 20 times that of solid lead. The shots of its interior near the end of the movie show that it's mostly hollow, so that means the material it's built out of would have to be at least the density of white dwarf matter, if not neutron star matter (neutroniuum).
* Subverted in ''Film/SecondhandLions'': Walter correctly figures out that Garth couldn't have taken out the guards with all that gold weighing him down, leading him to admit "[[RetiredBadass Hub]] might have helped a little" and a cut to young Garth struggling to do anything.
* Averted in ''Film/TheWayOfTheGun''. When the kidnappers ask for $15 million in the classic "small, unmarked bills," Taye Diggs' character can be heard yelling into the phone "Do you know how much that will weigh? Try a couple hundred pounds!" In the director commentary, Christopher [=McQuarrie=] says this came about when Benicio Del Toro, during filming, actually asked how much $15 million would weigh. The money eventually comes in three large dufflebags which are generally shown to be quite heavy. Not a complete aversion, as $15 million would still weigh more and take up far more space than three duffel bags could handle, but at least it wasn't the classic BriefcaseFullOfMoney.
* An Creator/IrwinAllen movie, ''City Beneath the Sea'', invoked the density of gold when the titular undersea colony used ingots as shielding to separate samples of an [[{{Unobtanium}} ultra-fissionable material]] and prevent it from achieving critical mass. And then an idiot thought, "Gold! I'll steal some!" without considering that a) he might cause a nuclear explosion, and b) the gold he wanted to steal was being irradiated. [[FridgeLogic To be fair, the filmmaker didn't seem to consider the second point either]].
* In ''Film/KellysHeroes'', TheCaper involves a squad of Allied soldiers in WorldWarTwo stealing $16 million in [[NaziGold gold bars]] from a bank behind German lines. In the WW2 era, the price of gold was fixed at $35 per troy ounce, so $16 million worth would weigh 15.67 U.S. short tons and have a volume of 26 cubic feet. It has been calculated that the writers grossly misrepresented the size and weight of that much gold given how much is visible in the movie and the means they use to carry it away.
** Boxes filled with bullion are also tossed around as if they were empty (which, of course, they are), when, given the size, they would weigh several hundred pounds.
* [[SoftWater Water is soft,]] and according to many, many disaster movies, very light. [[MostWritersAreHuman Most of us use water every day,]] and we expect it to flow around anything it encounters that is denser than air. However, one liter (1 cubic decimeter) of water weighs one kilogram. This means that every cubic meter of water weighs 1,000 kg, or 2,204.6 lbs. ''This'' means that a 7-foot wall of water hits a building with 3.1 pounds per square inch, which is comparable to an explosion at close range. Now, scale this up to the 300-foot wave in ''Film/TheDayAfterTomorrow'' or the 3500-foot wave in ''Film/DeepImpact''. Bomb shelters built to withstand megaton nuclear blasts ''might'' survive, but they would be very hard-pressed.
* In ''Film/HarryPotterAndTheDeathlyHallows Part 2'', the trio are in a vault at Gringotts where thousands of gold items are cursed to multiply whenever someone unauthorized tries to move them. Harry swims through a growing avalanche of them when he should actually be pretty quickly crushed, or should at least break a lot of bones and be rendered immobile. However, since gold has been said to be one of the few non-transfigurable materials, the duplicated objects in the vault can't turn into real gold, just something that looks like it.
* In the 2002 film ''Film/GhostShip,'' two men can lug around ''crates'' of gold bricks that in real life would require very heavy machinery.
* In ''WesternAnimation/TheThiefAndTheCobbler'', you can see the gold balls ''bounce around'' like rubber despite making metallic noises. Granted, the movie isn't realistic in the ''slightest'' bit, (they don't even lose momentum!) but you'd assume that gold balls wouldn't bounce ''that'' effortlessly. Heck, due to gold's relative softness, if they fell on a hard surface hard enough to bounce they'd deform or dent instead.
* Almost at the end of ''Film/TheFog'', when Father Malone picks up the gold cross, an object this size made of solid gold should have weighted al least 100 kilograms, probably more. To the credit of the actor, you can see him struggling to carry all this weight, but he shouldn't have been able to carry it alone. Specially problematic is when he lifts the cross with only his arms to hand it to the ghost, and keeps it in this position for a non-trivial amount of time.
* ''Film/BattlefieldEarth'' pretty much treats gold as weighing about as much as steel. It's hard to tell exactly, though, since the antagonists have an undefined level of super strength, and they're the ones most often seen handling gold.
* Played egregiously straight in ''Film/TowerHeist'', where a [[spoiler:car made of solid gold]] is handled as if it weighed less than one made of steel, and does not seem to weigh down neither the [[spoiler:scaffolding crane]] nor the [[spoiler:elevator]] that are used to transport it.
* Plutonium in ''Film/TheExpendables2'' is contained in sealed containers that are easily carried by hand. Said containers are generally made of lead-lined steel and would weight in at twenty kilos, and would be a challenge to carry at best.
* Averted in ''Film/ReturnFromWitchMountain''. Tony has been put under mind control, and uses his telekinetic powers to steal a huge display of gold bars from the middle of a museum in broad daylight (after first causing mass pandemonium so nobody notices the theft). He effortlessly uses his powers to float the brick-sized bars of gold out of the building (no problem, it's magic), and to the man waiting with the getaway car. The man sees the brick floating slowly towards him and reaches out to pluck it from the air...and is immediately thrown back a couple of steps from the force of the impact. As he's righting himself, a second brick knocks the wind out of him, and a third knocks him sprawling to the ground. The remaining bricks float over his head and completely crush the getaway car into the concrete before Tony and the other two thieves come outside. A bar of gold typically weighs something in the range of about 13kg, and the car was flattened under probably at least a couple of tonnes of it.
* In ''Film/DangerDiabolik'' (best watched in [[Recap/MysteryScienceTheater3000S10E13Diabolik the MST3K incarnation]]), the authorities melt 20 tons of gold into one huge bar to move it and entice the protagonist to try to steal it. That much gold would make a cube about 3.5 feet in each direction -- about the size of a small refrigerator -- but they make a bar nearly as long as a train car, several feet wide, and a few feet high -- at least 300 tons worth, at a rough estimate.
** To top that off, the protagonist crashes the train into a bay and then is able to float the gold container away with nothing more than a dozen party-sized balloons.
* A solid gold object the size of the idol at the start of ''RaidersOfTheLostArk'' would weigh at least fifty pounds, far more than Indy's small bag of sand. When Indy looks at it, he actually removes sand from the bag to approximate its weight and later events even suggest that he guessed too low. While it's never explicitly stated that the idol is ''solid'' gold even a hollow gold object that size would be much too heavy to be toted around as easily as it is.
[[/folder]]

[[folder:Literature]]
* Invoked in ''Sharpe's Siege'' by Bernard Cornwell - Sharpe and his Confederates are accused of stealing the Imperial Treasury of France (they didn't). [[TheLancer Captain]] [[TheCaptain Frederickson]] points out that the court is accusing them of removing four tons of gold, in small wooden boats, whilst under enemy fire. However, this defense doesn't work, because of the [[MilesGloriosus arrogant]], [[UpperClassTwit aristocratic]], [[GeneralFailure incompetent]], [[GungHolierThanThou pretentious]] and [[BlueBlood snobbish Colonel Wigram]] presiding over the [[KangarooCourt kangaroo court martial]].
* In an ''Literature/EncyclopediaBrown'' story, the density of gold was used to prove that the supposed gold ingots were really just bricks spray-painted gold, as there is no way a kid could lift a brick-sized bar of gold with one hand. Although if you're dumb enough to confuse a spray-painted brick for real gold...
* In the ''Literature/HonorHarrington'' books it was initially played straight, despite Creator/DavidWeber [[ShownTheirWork getting quite a bit else right]]. Once fans started pointing out the absurdly low density (on par with cigar smoke) with the largest ships, the numbers were fixed.
* In Creator/TerryPratchett's ''Discworld/TheTruth'', Lord Vetinari is accused of trying to abscond with a large amount of money supposedly stolen from the city's treasury. Commander Vimes and William de Worde both realise the story can't be true after they calculate how much that amount of money would actually weigh.
* Pavel Bazhov's ''Malachite Casket'' happily averts this -- it ''is'' a collection of miners' fairytales, after all. In one story the hero doesn't let himself to be deceived by the FairFolk because he knows ''exactly'' how heavy the gold is, so he immediately sees that the teenage girl effortlessly holding a tray full of gold sand, ingots and lumps (that would weigh hundreds of kilos in RealLife) is a fake.
** In another story two boys who do not know this yet find come across magical gold which, if picked up, shouldn't be dropped, or all the gold will turn into rock. One boy grabs happily a large lump and suddenly finds it unbearably heavy, but is too afraid to drop it and just warns his friend. The latter picks up much smaller, but still heavy piece and realizes that his friend is way over-encumbered. After an argument, the second boy deliberately drops his lump, so all gold turns into rock and his friend won't hurt himself.
* Damien Lewis's ''CobraGold'' completely averts this, the problem of getting 17 tons of gold out of Beirut is central to the story in the first half, and finding a suitably heavy fake (which turned out to be solid tungsten coated with a thin layer of lead and gold) later on, is included as well. There are numerous mentions of how little space 17 tons of gold actually takes up, but most of their equipment can't handle the heavy load all at once.
* Averted in ''Literature/TheHobbit''. Bilbo has helped the dwarfs reclaim the Lonely Mountain, and can theoretically claim 1/14th of Smaug's hoard. What does he take? One chest of gold coins and one chest of silver coins. That was all he conveniently transport home with a single pack animal.
** And of course the acquaintance and goodwill of many notable personages throughout the world, which is both fairly valuable and a lot easier to carry.
** And a mithril shirt which Gandalf later claims is worth more than everything else in the Shire combined. And a single [[ArtifactOfDoom gold ring]]...
** The dwarves also let Bilbo keep the treasures they found in the trolls' cave, presumably both to make up for the share of treasure he was leaving behind, and because they would be too busy rebuilding Erebor to head back that way for some time.
** He ''could'' have picked valuable jewels and works of art instead, but it's highly unlikely that anyone in the Shire could have paid anything close to their real value. The book also averts ArtisticLicenseEconomics!
** Also note that his treasure is worth enough for him to live a lavish life till he's 111 (Some sixty years after acquiring the treasure) and leaves for Rivendell, at which point he still has enough money left for his heir to be filthy rich.
*** Which just goes to show how incredibly rich the Dwarves of Erebor were and strengthens the Dwarves' motives for taking back the Lonely Mountain. A life of relative poverty when a treasure trove like that is lying around would be that much more unbearable.
* Averted in the ''{{Belgariad}}'' novels. When at a formal dinner in Mal Zeth, Belgarion is informed that he's in a position to make millions. Belgarion replies that he couldn't carry it: he knows how much that kind of money weighs. Polgara uses a similar argument when deciding to not empty out her account in the Sendarian royal treasury, taking only a minuscule percentage of the money for expenses (She also good reason to wish to be inconspicuous, which being visibly wealthy would interfere with).
** At one point, Belgarath has to ransom Polgara from her [[ItsALongStory Nadrak master.]] He finds five ''small'' bars of gold all he can conveniently carry.
** Of course, both ''could'' move the weights if they wanted to; the real reason is probably that they know economics very well via long experience, are investing in the preservation of countries rather than account balances, and have no serious use for money anyway.
* Averted in the second ''Literature/AlcatrazSeries'' book, when the titular hero plans to take gold bars with him. He stuffs some into his pockets, and [[LampshadeHanging lampshades this]] by commenting on how gold was actually very heavy. He later needs to toss some of the gold away to keep up with his allies.
* Averted in ''Literature/{{Cryptonomicon}}'', where the protagonist mentions the weight of a gold brick as one reason why moving lots of gold bars by chopper or by Jeep across the deep jungle is impossible.
* ''Literature/JamesBond''
** Subverted in the short story "[[Literature/OctopussyAndTheLivingDaylights Octopussy]]". The main character carries a briefcase containing gold to bypass customs. He takes amphetamines to be able to lift it easily enough to conceal its weight.
** Played straight in ''Literature/{{Goldfinger}}''. The deconstruction mentioned above, in the Film category? Exclusive to the film; in the original novel, Auric Goldfinger ''really was'' just going to rob Fort Knox.
* In the first ''HisDarkMaterials'' book, Lyra escapes her captors by shaking out a bag of flour, running out of the room, and then waiting for the flour to explode. First, a large bag of flour would be too heavy for someone Lyra's size handle in that manner. Second, individual grains of flour are too heavy to drift in the air for that long a time.
* Averted in the novel The Delta Decision. A member of a terrorist group that has just hijacked a jetliner demands a payment of one million gold Krugerrands (a coin made of one ounce of gold). A member of the negotiating team, who is also an operative in an elite anti-terrorist military unit, tells the terrorist that one million gold Krugerrands is going to weigh over 30 tons, and how do they intend to transport it? The shocked reaction of the terrorist lets everyone know that the terrorists didn't think of everything, which makes it less surprising when all of the terrorists are killed.
* Averted in the first ''Literature/ArtemisFowl'': Artemis' demands are one metric ton of gold, brought on an anti-gravity trolley so a five-foot-tall fairy and an eleven-year-old can push it around easily. Butler easily picks up an ingot, but he's almost seven feet tall and "has muscles like a Michelangelo statue".
* WE Johns fell into this trap in the novel ''{{Biggles}} and Co'', when a recently-demobbed Biggles was hired by a major bank who've been hit by a string of {{ArmedBlag}}s and think air-freighting their gold bullion might help. It doesn't; the gang responsible get hold of a small stunt-plane and a few machine guns and turn SkyPirate... but Biggles put the real gold under a false floor in the aircraft's cargo hold, and the robbers drive off in triumphant possession of a large quantity of lead. Now, the author makes an effort at a HandWave by never quite specifying how much gold is being transported, stating only that the individual crates can be lifted comfortably by two men. But nevertheless, carrying a significant amount of gold ''and'' an equivalent number of crates full of lead would be an impressive feat indeed for the cutting edge of 1920s aerospace engineering!
** Averted in one other way in the same story, though. [[FridgeLogic You might think]] the robbers would notice that the decoy crates were a bit lighter than they should be since lead is somewhat less dense than gold, but the explosives Biggles packed into each crate and wired to detonate when the lid was lifted[[note]]he had something of a vindictive streak as a young man, but mellowed in later books[[/note]] might've gone some way to making up the weight.
* ''ByTheGreatHornSpoon'' uses this twice. The first when the BattleButler knocks out a huge dude with a single punch. He's regarded as a MemeticBadass from that point onwards, due to the gold dust in his gloves giving it a lot of extra weight. The second when the same man, having struck it rich, falls overboard, and has to lose his clothing (which contained a large amount of his acquired gold) to avoid drowning.
* An argument about whether or not [[http://en.wikipedia.org/wiki/Anchor_ice anchor ice]] exists kicks off the plot of Creator/{{Jack London}}'s short story ''The Men of Forty Mile''. The solution? A ''duel to the death''. Ultimately, [[spoiler:they don't go through with it after a third party intervenes.]]

[[folder:Live Action TV]]
* On ''Series/ThirtyRock'', Kenneth has an idea for a game show in which contestants guess which suitcase being carried by models is filled with gold. The show was discontinued for being too easy, as one had only to look for the model who had trouble holding up the suitcase. This perhaps qualifies as both a lampshade ''and'' a straight example of this trope; even a small briefcase will have a volume of some 1,000 cubic inches, so one ''full'' of gold would weigh over 700 pounds. By comparison, the current deadlift record is just over 1,000 pounds, so you'd need to be a seriously ripped professional strongman to move that briefcase.
* At the other end of the scale, one episode of ''Series/{{CSI}}'' has the team investigating a casino heist, supposedly of ten million dollars in cash. Grissom realizes the money would weigh around two hundred pounds -- far too much for one man (seen in security footage) to practically carry. (It isn't stated, but it would also be unfeasibly bulky.)
** The 200 pounds (actually closer to 220) presumes it's all in $100 banknotes. A more normal mix of currency would about double this. A million US dollars in mixed currency fills a large suitcase, and one would probably have to pay over-weight charges to fly with it. $250,000 (in $100 bills) fits carefully into an DiabolicalMastermind-style aluminum attache case.
*** Note, however, that having it all in $100s is not actually an unreasonable assumption for a casino heist, as the casino presumably sorts the cash, and a smart thief with limited resources would probably want to take his/her whole heist in the form of $100s if possible.
* In ''Series/{{Merlin}}'', a character uses alchemy to create a big lump of solid gold, which the characters lift and carry as easily as if it was polystyrene.
* A DVD commentary on ''{{Smallville}}'' pointed out this trope to highlight actors John Schnieder's acting abilities. In a scene where Johnathan Kent and [[{{Superman}} Clark Kent]] are moving bales of hay, Johnathan is visibly having a hard time carrying the prop hay. The production staff had forgotten real hay bales do weigh a lot and Schnieder, who had had some farm experience, decided to portray this right. The actor playing Clark Kent had no such experience, but given [[SuperStrength who he is]], it actually helped to make the two characters believable.
* Appeared in an episode of ''AmericanJustice'', discussing the case of a woman who had killed and dismembered and beheaded a man, the video of her statement has her comment on picking up the head and being surprised at how much it weighed. A detective who'd worked the case commented that's one of the reasons they were confident the confession was valid: unless you'd actually picked up a detached head, it's not the sort of thing someone would think about.
* Played with in ''{{Sharpe}}'s Rifles''. Sharpe is assigned to escort a party carrying a box that, to allay suspicion, they claim is full of old papers and documents. However, they lift the box around with ease invoking this trope. After Sharpe (and the audience) have accepted that, Harper conversationally points out that they are being hoodwinked because paper weighs ''a lot'' and whatever the box contains is very light. [[spoiler:It is actually a flag that is a cultural treasure and propaganda rallying point]].
* ''Series/TheTwilightZone'' episode "The Rip Van Winkle Caper" plays this straight when some gangsters steal a truck full of gold and hide out in a cave where they hibernate for many years. When they wake up, they crash the truck trying to get back to town, and hike back to town instead, carrying backpacks full of dozens of gold ingots each. Later on, one man drops his canteen and the other offers him a drink for a bar of gold - he eventually ends up with both their shares of gold on his back, but doesn't even slow down.
* Averted, surprisingly, in an episode of ''Series/{{Batman}}'', a series not usually known for its scientific accuracy. In an episode in the third season, Egghead steals two pounds of radium in order to hatch a dinosaur egg (see previous comment about scientific accuracy). Egghead handles the box of radium as if it were very heavy—the radium only weighs two pounds, but the lead shielding adds a lot more.
** Played basically straight in another episode—also starring Egghead, coincidentally—he pilfers a giant egg (maybe three feet long) made of solid gold. No one short of the Incredible Hulk should be able to lift that thing, but Egghead picks it up and carries it out, though he's straining with the effort and can't lift it above his waist.
* Humorously subverted in season 4 of ''Series/BreakingBad'': when the amount of money that Walt brings in proves too much to launder through the car wash, Skyler tries to hide several hundred thousand dollars in cash by sticking the bills in vacuum bags between little-used clothes and hanging the bags in the closet. The bags weigh so much they break the closet's hang rod, so she stores the vacuum bags (clothes and all) under the floorboards instead.
** That was not even the first time the show subverted this trope; it happened once before in season 3 when Hank was helping Walt move out of his house. Walt sees his Duffel Bag O' Cash™ sitting on the driveway and moves to grab it before Hank does, whom insists on grabbing it anyway. "Jesus, what've you got in there, cinder blocks?", to which Walt replies with a straight face "[[CassandraTruth Half million in cash]]." Hank laughs it off as a joke. Subverted even further by the bag making an appropriately loud thud when it lands in Hank's trunk.
* Averted in ''Series/TheAdventuresOfSuperman'' when a criminal, dressed as Superman, and his cohorts hijack an armored car carrying gold ingots. The robbers visibly struggle with the weight as they carry the ingots one by one from the armored car to the getaway vehicle.
* In ''Series/WhiteCollar'', a briefcase full of Krugerrands was quite easily passed around, while in reality that much gold would have weighed about a hundred pounds.
* ZigZagged in an episode of ''Series/HogansHeroes'': The crew paints some gold bars red and some bricks yellow to swap them with each other, and they have to pretend that the regular bricks are really heavy when transporting them. But they make a set of stairs into Klink's office out of the gold bars which don't sink into the ground.
* Averted in an episode of ''Series/SquareOneTV'' 's ''Mathnet'', where an angry judge imprisons people he believes were falsely found not guilty, even though they proved their innocence with math. One man says that the amount of gold he supposedly stole would have been impossible for him to carry.
* The trope appears at the end of a ''Series/SesameStreet'' Muppet and Kid Moment, in which Ernie and Bert teach Shola Lynch about the relative sizes of balls. After showing her a basketball and two smaller balls, Ernie shows Shola a ball bearing (she calls it a "baby ball"). Ernie then throws the ball bearing to Bert, but it flies off screen, followed by the sound of breaking glass.

[[folder:Mythology & Religion]]
* Detractors of the Mormon faith have often derided the idea of the Book of Mormon having been transalted from solid gold plates - particularly the idea that Joseph Smith says he had to run about a mile with the plates when he first recovered them. If the plates were solid gold they would have been very heavy, but if they were a copper-gold alloy (which is more likely) they may have weighed only around 60-70 pounds, a more reasonable figure for Smith, up to that point a manual laborer noted for his strength, to run with.[[/folder]]

[[folder:Table Top Games]]
* Classic ''BattleTech'' rated HumongousMecha by their total mass. Which is fine as far as it goes, but the fluff assigned height and width values to several of the more iconic chassis that would leave them with a low enough density to float on water. (I'm looking at you Atlas)
** This gets hilarious when various 'Mechs are depicted with other units or infantry for scale. For instance, the relatively diminutive Wasp is twenty tons and explicitly stated as six meters tall in one book, while the aforementioned Atlas is described as sixteen meters tall and one hundred tons. If both were scaled to similar heights, the Wasp would be over 3.75 times denser than the Atlas.
** It gets worse with [=DropShips=]. The Union class, for example, is basically a sphere eighty meters across. That is, about 270,000 cubic meters... 3,600 tons fully loaded.
* First Edition ''[[TabletopGame/DungeonsAndDragons Advanced Dungeons and Dragons]]'' went too far in the ''opposite'' direction: all coins were assumed to weigh a whopping 1/10 of a pound each. This would make one gold piece bigger and heavier than almost any gold coin known to exist in real world history.
** In early versions of D&D, the logistics of getting any treasure found back ''out'' of the dungeon were very much intended -- [[GuideDangIt if not always spelled out as such]] -- to be part of the challenge. Downplayed in later editions.
* Although ''TabletopGame/{{Pathfinder}}'' acknowledges that gold is ill-suited to adventuring gear, ''Ultimate Equipment'' states that weapons and armor made of solid gold weigh 50% more than normal. That number would more accurately be 2.4 times heavier.
[[/folder]]

[[folder:Video Games]]
* Many games featuring weight limits for what a character can carry measure everything in the same unit. This can become a problem when the unit was designed with some common adventuring item (such as an arrow or dagger) weighing "1 unit," in which case items that should be much lighter (jewels, scrolls?) end up weighing the exact same amount as "base" items. A common workaround is to give such items a weight of zero, which can [[HyperspaceArsenal lead to massive hoarding]] if any of them are common and useful.
** In lieu of such possible hoarding, certain games may opt for body slots for items of negligible weight, meaning only a certain number of these items may be worn at a time.
** And since it keeps coming up, many of these games give you a strict limit to how much equipment you can carry, say, 100 lbs. And then lets you carry around, on your person, hundreds of thousands of units (typically coins) of gold which [[WalletOfHolding don't factor into encumbrance]] ''at all''.
* Most fantasy C[=RPGs=] (such as ''VideoGame/NeverwinterNights'', ''VideoGame/BaldursGate'' and ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'') track encumbrance on items, but money is weightless, so it's permissible to walk around with five million gold coins without a sweat. On the other hand, the [=RPGs=] some of them are based on usually averts this: in D&D 3.5, 50 coins weigh [[AmericanCustomaryMeasurements a pound]]. Whether you take this into account depends on your DM.
** The problem with various {{Role Playing Game}}s, especially those based on on (A)D&D is the cost of not so rare items that sometimes reaches hundreds of thousands "gold pieces". This is actually magnitude of late medieval war contributions and budgets of duchies or smaller kingdoms.
** ''AsheronsCall'' originally averted this but they changed it later.
** ''{{Albion}}'' averts this - money has a definite weight.
** And old dungeon crawler computer game called ''VideoGame/CastleOfTheWinds'' completely subverts this trope: not only does the money have weight but also mass, which means the more you try to lug around the slower you move and react when the ancient red dragon comes around the corner. Fortunately, there's a bank in the village you can deposit all your cash in for a letter of credit. This is actually correct (letters of credit were reinvented in the late Middle Ages - the Romans were using them over a thousand years before). However, it's still noteworthy that copper, silver, gold and platinum pieces weigh exactly the same, while being conveniently worth ten times the value of their predecessor.
** ''{{GURPS}}'' takes some time to discuss this. The writers point out that adventurers without superhuman strength wouldn't be able to carry off piles of gold. Gold coins ''are'' pretty heavy but in a fantasy setting gold, especially in the form of jewelry, would have had a better value/weight ratio than we think of today.
** Averted by ''ReturnToKrondor'', where coinage had a definite weight. However, it wasn't very noticeable for the first few chapters of the game, where it would auto-exchange coins for high-value gems whenever you visited a shop. Towards the middle of the game, there's a chapter that involves traveling from Krondor to a small village, with no shops to stop in along the way to exchange coins. You will inevitably be leaving behind quite a large amount of treasure on monster corpses before the chapter is up.
*** ''VideoGame/BetrayalAtKrondor'', the predecessor to ''Return'', used weightless money. Then again, inventories were so small that requiring an inventory slot for money would've been outright painful.
** ''VideoGame/NetHack'', based on early D&D rules, has gold coins as the main currency (they're called "Zorkmids", but the game makes it clear they are made of gold), and defines 100 gold coins as 1 unit of "weight". This still makes them a great deal lighter than most other items (scrolls of parchment are 5 units of weight).
* The info in the Pokédex in ''Franchise/{{Pokemon}}'' frequently applies this to living things, giving weights that are often ridiculously heavy or light: Wailord is 14.5 m long, yet only weights about 400 kg.
** Apparently some Pokémon are ''less dense than hydrogen.''
** The whale family are at least called "float whale Pokémon," as Wailord is likely based on a blimp and its original form, Wailmer, seems to be based on a beach ball. However, how they manage to dive is the real question.
** Also, sometimes in the anime, people are shown carrying Pokémon whose Pokédex entry gives them a considerable weight with more ease than the average parent holding a baby for extended periods.
** This is one of the reasons for the {{Fanon}} theory that the ten-year-old player character in the games is the one writing the Pokédex entries. He/she is just making up numbers that sound right to them and wildly over- and underestimating everything in the process.
* ''{{Tibia}}'' averts this, treating gold as a stackable (up to 100 per slot) object. 100 of them equal a platinum coin and 100 of those equals a Crystal coin.
** Maybe you automatically visit a bank during loading screens or something?
* ''Franchise/TheElderScrolls''
** In ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'', everything has a rather realistic weight to it, however, your character can still lift an insane amount without being slowed down. Humorously, this means often times it's more practical to steal/loot cheaper stuff (like clothes) than gold, because its value:weight ratio is higher and thus you can walk away with more of it.
** In ''[[VideoGame/TheElderScrollsIIDaggerfall Daggerfall]]'', when the shop had been bought out of its money, a nondescript letter of credit was issued. You could never be over-encumbered with too many 0.25lb pieces of paper placed directly into your inventory by shop-keeps. On the other hand, you could never pick up anything else until you returned under normal inventory weight limits.
** In ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'', all ingots of metal weigh the same (1 unit). This includes gold, which would obviously be much denser. And gold coins are not counted towards your weight limit, meaning you can potentially have tens of thousands of coins in your pockets with no effect on your carrying capacity.
*** The crafting system leads to some amusing math as well. For example, a 3-pound bear pelt yields 4 pounds of leather.
* Many games with a storage system will often overlook that the amount of items and weight of some of them will either not fit in the specified container used, or would end up being so weighty and bulky the character couldn't move around as effectively as they are shown to. Of note, ''MetalGearSolid3'' comes to mind with its backpack inventory system, fitting an RPG, two rifles, and an assortment of pistol sized weapons, along with medical supplies, rations, and any critter you caught, while not weighing Big Boss down. They only become weighty when equipped on his person.
** In ''{{Minecraft}}'', the player can carry nearly 45,000 metric tons, and a 12-meter cube can be broken down and placed into a <1 m chest.
** Also is ''VideoGame/ResidentEvil4'', with the Attache case. Never mind an RPG weighs a lot, or that a fully loaded case would probably be too heavy to lift. And how does the Merchant hide that in his coat?
** Don't forget Link in...well, every ''Zelda'' game ever. But especially ''VideoGame/TheLegendOfZeldaOcarinaOfTime'', where he can swing his giant hammer almost as well as his sword, and the Iron Boots only make him sink if he's wearing them -- not while he has them stored inside his other boots (or wherever it is that they go).
*** In ''VideoGame/TheLegendOfZelda'' Link carries around with him, on top of the usual armour of shield, sword, bombs, arrows, etc, an entire raft and a ladder big enough to bridge small streams and gaps with.
** ''EverQuest'' assigned weight to coins, as well as having money come in different denominations (copper, silver, gold and platinum). Along with the way fall damage was calculated, it meant it was entirely possible to commit unintentional suicide by grabbing a couple thousand platinum from the bank - and abruptly taking 20k damage from the "drop" when you stepped off the threshold of the bank's front door.
** ''[[VideoGame/AncientDomainsOfMystery Adom]]'' also assigns weight to gold pieces. It's quite possible to get crushed under the weight the gold you are carrying if your magic fails you. With normal in-game methods you can accumulate hundreds of kilos of gold. Abusing a bug you can get hundred thousand kilos.
* In ''{{Uncharted}}: Drake's Fortune'', Nate realizes the golden statue they're looking for was brought to the island when he looks at some old freight logs and notices something weighing "about 500 pounds". A cube of gold that weighed 500 pounds would have about 8.94 inches (22.7 cm) to a side. The statue they find looks like it should weight several ''tons'' at least.
** But then, [[spoiler:the statue isn't solid]].
* Not sure if it's a subversion or what, but in ''VideoGame/MafiaII'', one level has you giving the Chinese Mafia money in exchange for heroin. One of the head guy's bodyguards hefts the briefcase then tips it out, stating the denomination of the bills, their weight and how much that weight equals in money.
* In the VideoGame/{{Fallout 3}} expansion ''The Pitt'' you are sent on a quest to collect 10 steel ingots out of a possible 100. Each steel ingot weighs 1 pound. If you collect them all before turning in the quest, [[AntiFrustrationFeatures their weight won't count against your carry limit]]. If you collect some, complete the quest, and then go back for the rest, the remaining ingots will each weigh their full amount.
* The first expansion for ''VideoGame/FalloutNewVegas'', ''Dead Money'', subverts this at the end when the player finds a vault with 37 gold bars. Each bar is worth 10,439 caps, a ridiculously large amount, but each bar also weighs 35 pounds. You're under a strict time limit to escape with whatever you can carry, and if you carry more than your encumbrance limit, you move far too slowly to make it out. If a player wanted to take all the bars—a total of 382,913 caps, enough that you'd basically never need money again—s/he would be carrying 1,295 pounds. The highest possible carry weight a player could have (i.e. max Strength and various Perks) is 375 pounds, so a player could only carry 10 of the bars at most without being over-encumbered, and they'd have to drop everything they were already carrying.
** To make this all sillier, no vendor in the game ever has more than 8,000 caps. It's impossible to sell even a single bar for its total value. Some have speculated that this is meant to tie into a theme of letting greed go. (The natural progression is to take out some in trade, but even then it is difficult to find a vendor with that much to spare.)
*** It's entirely possible to leave the vault with every single bar through clever use of the game world, [[GoodBadBugs by loading the gold into a dead body, decapitating it and carrying the head manually.]]
** New Vegas also features a partial aversion to this with "Hardcore Mode" - where (among other things) ammo has weight. At first, it doesn't make much of a difference when individual bullets weigh 1/15 to 1/10 of a pound - but when players start acquiring automatic weapons that eat bullets like candy, or come across rocket launchers whose individual rockets weigh two pounds apiece, it really starts to cut down on what you can carry compared to normal mode. (Though even in hardcore, there are many completely weightless items - including gunpowder and shell casings.)
*** This is made more annoying by many junk items used for crafting being exactly 1 pound, even if it makes no sense. Somehow a scalpel, forceps, and a ''single tin can'' all weigh a whole pound each.
** Both ''Fallout 3'' and ''New Vegas'' have an ItemCrafting component called a fission battery. They're the size and shape of 9-volt batteries, yet weigh ''10 pounds'' in ''Fallout 3'' and 6 pounds in ''New Vegas''. A [[ILoveNuclearPower portable fission battery]] would be denser than a regular battery, since nuclear fuel and shielding are both heavy, but a 10 pound object that size would be ten times the density of ''pure uranium.''
* Lampshaded in the ''VisualNovel/UminekoNoNakuKoroNi'' fan novel [[RPGEpisode "Witches and Woodlands."]] Those who wager their weight in gold in [[{{Greed}} Mammon's]] trial and lose are [[TakenForGranite turned into gold statues]] to pay the debt. George protests that the density of gold means that the statues would weigh more than the living victims. [[GameMaster Beatrice]] hastily handwaves it by saying that the statues are hollow before muttering, "Damn, I hate science! Always messing with my magic."
* ''PayDay2'' averts this when the criminals abscond with their take, as their speed depends on what they're carrying. Carrying a rack of jewelry will barely slow a thief down, but carrying a duffel bag full of money keeps theives from being able to jump or run. Carrying a bag of gold ingots will slow a thief to a crawl.
** This is played straight, however, when characters can throw each bag effortlessly, making it faster to constantly throw a bag of gold forward then pick it up as opposed to simply carrying it. (The developers noticed this as well, and with tongue-in-cheek referred to their game as a "bag throwing simulator.")

[[folder:Webcomics]]
* [[http://www.airshipentertainment.com/growfcomic.php?date=20070506 These]] two [[http://www.airshipentertainment.com/growfcomic.php?date=20070513 pages]] of ''ComicStrip/WhatsNewWithPhilAndDixie'' feature exercises for ''DungeonsAndDragons'' players to get a feel of what they put their characters through without a second thought. Number 1 is acquiring treasure, demonstrated with bowling balls.
** The strips however fall into the trap of assuming plate armour and swords are too heavy for an average person to use easily. In reality, medieval knights' plate armour was light enough to cartwheel and swim in, and a large sword weighed about 2 pounds.
* PlayedWith in ''WebComic/SchlockMercenary'': [[ActionGirl Elf]] carrying three large cylinders evidently made of solid gold is not a problem, as she is in strength-enhancing PowerArmor. However, she declines Kevyn's suggestion of leaning them against a bulkhead:
-->'''Elf:''' They weigh about a half ton each. I'm not leaning them against '''anything.'''

[[folder:Western Animation]]
* In ''WesternAnimation/TheBatman'', the Joker once stole Bane's muscle inflation device, and used it to become super-strong and grow at least fifteen feet tall. He later uses this SuperStrength to lift a solid gold globe, but the thing's shape isn't changed by doing this. Weight aside, gold is fairly soft; trying to lift a huge globe of solid gold (or worse a hollow sphere of gold) would result in a Joker-shaped dent on the under side.
** In fact, large objects impossibly retaining their structure when lifted by a human with one spot is ''very'' common when it comes to the portrayal of SuperStrength, so much that part of the common "Tactile Telekinesis" {{Handwave}} is that their RequiredSecondaryPowers are holding the object together.
*** Although only the new Superboy (Kon-El/Connor) actually has it on his power list. [[LuckilyMyPowersWillProtectMe He would mention he was using it. All. The. Time.]]
* The episode of ''WesternAnimation/BatmanTheAnimatedSeries'' that debuted Scarface has a scene where his men are stealing a load of platinum. They unload the ingots one at a time and it's shown that of the three, only Rhino, who's twice the size of Batman, can lift an ingot with no problem. Batman is captured in the ensuing fight when Rhino tips what should be several tons of the stuff over. Surprisingly, Batman is only knocked out for a few hours with no noticeable injuries.
* In TheStinger at the end of ''WesternAnimation/FindingNemo'', the water in the fish bags floats completely above the water in the ocean despite the bags coming from a seawater aquarium and being at the surface of the ocean (where the water is least dense).
* ''WesternAnimation/{{Futurama}}''
** Parodied; starship fuel (dark matter) is so dense that "a single pound of it weighs ten thousand pounds." In one case, Fry refers to a ball of this fuel, which has previously been shown on rare occasions to be lift-able by a human, as "weighing as much as a thousand suns." The episode "The Game" throws the dark matter's weight out the window by having the characters pushing ''wheelbarrows filled with it''. On the Sun.
** [[LampshadeHanging A lampshade]] gets hung on this when Fry and Leela are going to have a fiddle contest with the Robot Devil where the prizes are Bender's soul and a solid gold fiddle. When Fry ([[SmartBall of all people]]) asks "Wouldn't a solid gold fiddle weigh hundreds of pounds and sound crummy?" The Robot Devil admits that it's mostly for show. Nevertheless, Leela picks the fiddle up and attempts to play it moments later, and it seems to be an ordinary fiddle.
** There was also an episode where they go to a planet where the gravity is extremely heavy (as the professor says "You'd be crushed by the weight of your own hair"). Pillows weigh hundreds of pounds and raindrops can knock someone down. The crew tried lifting all the pillows at once and the dolly they were using fell apart almost instantly.
* Averted in an episode of ''InspectorGadget'', Penny realizes that a stack of gold bricks is fake because she can lift them too easily.
* ''LiloAndStitch'': Stitch is too dense to be able to swim, yet David and even five-year-old Lilo are able to pick him up with no more effort than they might expend lifting a corgi. Oddly not as unrealistic as it looks, since the basset hound is a real-life example of a dog too dense to swim more than a very short distance. While a strong swimmer like David should be able to rescue him; Lilo's ability to carry him is a little more far-fetched (bassets weigh 35 to 50 pounds, nearly as much as Lilo herself should weigh).
* One episode of ''MummiesAlive'' featured the ghosts of Gold Rush prospectors as villains, and they went around stealing every bit of gold they could find. Including BigGuy Armon's golden arm. Now, being the BigGuy it's not such a strain that he can make use of an arm made of gold, but their twelve-year-old friend Presley can lift it as easily as if it was made of cardboard.
** In ''Who's who'' however when Rath and Armon have their minds switched, Rath is unable to properly use Armon's golden arm as even with Armon's muscles and size, he isn't used to carrying such a large weight.
* They carry stuff made out of solid gold rather effortlessly in ''Anime/TheMysteriousCitiesOfGold''.
** To say nothing of the Golden Condor, ''[[UpToEleven an airplane made out of solid gold]]''.
* Averted in ''PinkyAndTheBrain''. One of their first capers was to break into Fort Knox and steal all the nation's gold. Unfortunately, the two couldn't pick up even one brick.
* ''WesternAnimation/PussInBoots'' averts this in the scene where the heroes discover the golden eggs--they're too heavy for any of them to lift a single one, so they take the goose that laid them instead. It's played straight in every other scene with gold, where dozens of those same eggs are carried around in a single cart and casually thrown around, as well as Puss-in-Boots's flashback where Humpty is able to move around two huge bags of gold.
* In ''WesternAnimation/TheSimpsons'' episode "The Seemingly Never-Ending Story", Marge effortlessly lifts a huge bag of gold coins with ''one hand''. In reality, she would barely be able to use it.
* Partially averted in ''TheSpectacularSpiderMan''. The Enforcers try to escape a crime scene with as much gold as they can, but only the [[SuperStrength super-strong]] Ox can carry more than one bar. Earlier in the episode, however, an ''enormous'' stack of gold bars comes down on Spider-Man, and he's only briefly hindered. Even as tough as Spidey is, that much weight would have flattened nearly anything.
* ''WesternAnimation/SpongebobSquarepants'' is never terribly consistent about whether the characters are in a water-like medium or an air-like medium.
* Density is a plot point in the ''WesternAnimation/ThunderCats'' episode "All That Glitters", with the fuel source [[{{Unobtainium}} Thundrillium]] being stated to be ''denser than gold''. Granted, the [=ThunderCats=] are all pretty strong (even those whose skills ''don't'' have anything to do with power still have a ridiculous amount of musculature for someone never shown pumping iron), but for something to be that dense and still of use as anything but a permanent doorstop...
* [[WesternAnimation/DuckTales Scrooge McDuck]] can ''dive into the gold and swim in it''. However, when the triplets try to do that, they get hurt and [[LampshadeHanging wonder how does he do that]]. Maybe the gold likes ''him'', too, and just wouldn't hurt him?
** The same thing happens to the Beagle Boys in one of the comics, and to [[FamilyGuy Peter Griffin]] in one of their cutaways.
* The mecha tanks in ''WesternAnimation/TheLegendOfKorra'' are made of pure platinum so they won't be affected by metalbenders. Platinum is even denser than gold and is almost as soft; they shouldn't be able to stand under their own weight.
* ''WesternAnimation/JackieChanAdventures'': In "Bullies", Valmont uses the dragon talisman, which has the power of combustion, to rob Fort Knox. Jackie follows him there, and along with Uncle, each easily hold individual gold bricks. Uncles uses one to block a Dark Hand mook's punch ([[BondOneLiner "Respect your elders!"]]), and Jackie tosses gold bricks overboard [[IShallTauntYou in a mocking attempt to push]] Valmont's BerserkButton.

* At some old gold mines in Canada, one gag played on new miners (and visitors) was to tell them that if they could lift a brick of gold off the table with one hand gripping it from the top, they could have it. The joke worked because of the density (something about the size of an ordinary brick weighs about thirty kilograms), shape of the brick, and smoothness of the metal, making it impossible to get a grip strong enough to lift it.
** This was demonstrated in that exact fashion on an episode of the Canadian documentary series ''Ed's Up,'' which stars BarenakedLadies' Ed Robertson. While he was working at a facility which produces gold bricks, the employees told him if he could pick up the gold brick (the size of an ordinary brick) and carry it out without assistance, it was his to keep. The best he could was turn it on its side, after a great deal of effort. There was a slight lip on the brick after it had been stamped on the top, which he thought might help, but it was of no avail.
* Often, actors who handle fake human limbs without realizing that actual body parts are much heavier than you'd think they are. We tend to forget that because legs and arms seem to move around so easily. Of course, so do cars. Since it's something most people wouldn't really know about, it can be excused as a case of RealityIsUnrealistic. The weight of human body parts can be roughly calculated by the "rule of nines." The head is 9%, the torso is 18%, the abdomen is 18%, each arm is 9%, each leg is 18% (with 1% left over). So, if you weigh 80 kg (175 lbs), each of your arms is about 7 kg (15 lbs), and each of your legs is about 15 kg (30 lbs), give or take.
* There is a story about an 18th century nobleman trying to pick up a platinum ingot about 10 cm across. He then complained gluing the metal to the table wasn't funny.
* The specific gravity of gold is nineteen. That means it has nineteen times the density of water. Pick up a gallon jug of water and note how heavy it feels. If it was filled with gold it would weigh nineteen times as much.
* Anyone who ever found some iron pyrite, picked it up easily, and still thought it was gold instead of fool's gold has fallen victim to this trope.[[note]]The specific gravity of pyrite is about 5; the specific gravity of gold is 19.3. This means that a chunk of gold weighs about four times more than a chunk of pyrite the same size.[[/note]]
