History Main / ShrinkRay

** In the [[MediaNotes/TheSilverAgeOfComicBooks Silver]] and [[MediaNotes/TheBronzeAgeOfComicBooks Bonze Ages]], Superman had one that could be used to allow people to enter the Bottle-City of Kandor (which was originally shrunk by Brainiac using a shrink ray). Notably, Superman's shrink ray worked by exchanging one full-size person for one shrunken Kandorian, making them swap sizes. It was many years before he could find a way to enlarge all of Kandor on its own, and permanently, in ''Superman #338: "ComicBook/LetMyPeopleGrow"''.
** On the cover of ''Superman'' #365, ComicBook/{{Supergirl}} shrinks Superman down to tiny size with a Shrink Ray Gun as shown [[https://dc.fandom.com/wiki/Superman_Vol_1_365 here]].

[[folder:Comic Books]]* In ''ComicBook/AllFallDown'', the Order of Despots has one on the Moon, and threaten to shrink the Earth with it. It comes up again later as a possible solution to a ColonyDrop-sized asteroid [[spoiler: which turns out to be a hoax]].

* Creator/SidAndMartyKrofftProductions had an episodic kids' show called ''Dr. Shrinker'' in TheSeventies, in which five or six people were shrunk down to less than six inches.

[[folder:Puppet Shows]]
* Creator/GerryAnderson's lesser-known (and last) {{UsefulNotes/Supermarionation}} series ''The Secret Service'' features a shrink ray that Father Unwin uses to shrink secret agent Matthew to two feet tall. This allows Matthew to infiltrate the enemy's hideouts and learn their plans (allowing the 2-foot tall marionette to appear in full-size sets, occasionally hiding from full-size human arms and legs, or pets). It can also be used to literally bring the enemy down to size.

* ''TabletopGame/{{Champions}}''. When the power Shrinking is given the advantages Ranged and Usable On Others, it works as one of these.

* ''Carcosa: Weird Science-Fantasy Horror Setting''. Space Alien shrink rays can reduce targets to 1/10th normal size for 24 hours.

* In the Platform/ZXSpectrum game ''The Incredible Shrinking Fireman'', the titular character, whilst fighting a blaze at a factory, accidentally gets zapped by a shrink ray and must find a way to expand back to full size.
* ''VideoGame/DukeNukem3D'' has the Shrinker, an alien weapon that shrinks organic enemies[[note]]mechanical enemies don't even take damage from it[[/note]] for a short time, rendering them unable to attack or go very far; if you step on them, it's a OneHitKill, otherwise they'll return to their original size no worse for wear. There are at least two points in the game involving wall-mounted Shrinker ray shooters which Duke has to use to shrink himself so he can fit through very small passages; similarly, in one level you can shrink yourself by firing the Shrinker at a mirror, giving you access to a secret room. The ''Atomic Edition'' introduced the Protector Drone, an alien whose ranged attack is a Shrinker ray, and who can easily stomp Duke flat if he's shrunk. In all cases, Duke can NoSell Shrinker projectiles and immediately come back from being shrunk by using steroids.

* The unmodified de-noodlizer in ''VideoGame/ParappaTheRapper 2'' can shrink or enlarge characters (including Parappa) when a certain character presses the button on its remote control, even with help from the Guru Ant, of course.

* ''VideoGame/RatchetAndClankSizeMatters'' has one that Ratchet uses to go inside Clank.
* In ''VideoGame/TazInEscapeFromMars'', the first world has a shrink ray, and the rest of the worlds have them in edible potion form. These will temporarily shrink Taz, allowing him to through small passages, but also hindering his ability to burrow through the ground. Also in the first world, there is a ray that makes Taz grow.

* In ''VideoGame/CarmenSandiegoMathDetective'', Carmen has invented the Quantum Crystalizer, which shrinks objects and places them inside a gem, in order to facilitate her customary {{Monumental Theft}}s.

* Henry can use this in the third ''VideoGame/{{Henry Stickmin|Series}}'' game, ''Stealing the Diamond'', to make his way into the titular diamond's museum via a small crack, but this leads to a fail where he and a worm get into a fight and Henry loses and gets eaten.
* ''VideoGame/SoUhASpaceshipCrashedInMyYard'': Property of the MadScientist. Used to render a statue portable as part of the main quest.

* A shrinking device consisting of a platform and three laser turrets appears in ''VideoGame/{{Grounded}}'', although the player character(s) start out shrunken rather than using it to shrink like you'd expect. One of the unusual side effects of shrinking is amnesia, so you don't remember how you got miniaturized, at least at first. Other ArtisticLicensePhysics tropes apply as expected; you function more or less normally, and can move, carry things and eat normally without any consideration for the square-cube law.

%%* Steve thinks of creating one in [[http://www.irregularwebcomic.net/3451.html episode 3451]] of ''Webcomic/IrregularWebcomic''.

* In a commercial for [[Advertising/EnergizerBunny Energizer batteries]] featuring [[BumblingHenchmenDuo Boris and Natasha]] from ''WesternAnimation/RockyAndBullwinkle'', Boris attempts to shrink the Energizer Bunny with a shrink ray. He accidentally shrinks himself and Natasha instead, nearly getting them squished by the Bunny as a result.

* One of the recurring gadgets in ''Manga/{{Doraemon}}'' is a "Small Light". A flashlight-like shrink ray which shrinks any object and person down and does wear out eventually. There's also a "Big Light" which does the opposite. The small light getting stolen in ''Anime/DoraemonNobitasLittleSpaceWar'' even forms a plot point for the gang are stranded finger-sized most of the film until they can retrieve it.

* ComicBook/TheAtom had the ability to alter his size and weight at will. DependingOnTheWriter, he can also shrink other people and objects.
* ''Franchise/MarvelUniverse'': Pym Particles can shrink and grow things. Discovered by [[ComicBook/AntMan Hank Pym]], he uses them to both shrink and grow under the moniker of Ant Man/Giant Man/Goliath/Wasp/Whatever he feels like calling himself today. In ''ComicBook/GodzillaKingOfTheMonsters1977'', SHIELD contacts Giant Man to provide them with gas that shrinks Godzilla for more manageable size for several issues. [[RuleOfCool This results in Godzilla fighting sewer rats, then growing to human-size and beating up hoodlums in New York.]] The 'Big' G even gets a snazzy trenchcoat to rip off!
* In ''ComicBook/PowerPack'', the character with the mass powers, usually Jack, has the ability to shrink to miniature size but retains his full mass
* In ''ComicBook/AllFallDown'', the Order of Despots has one on the Moon, and threaten to shrink the Earth with it. It comes up again later as a possible solution to a ColonyDrop-sized asteroid [[spoiler: which turns out to be a hoax]].
* 1980's British ''Starblazer''. The Matter Condensor could shrink a cargo to a fraction of its normal size, enabling a small freighter to carry much more. Upon arrival the process was reversed.
* In ''ComicBook/SonicTheComic'', Nack the Weasel uses size-altering cartridges which fire a ray that can shrink things or make them larger.
* ''ComicBook/FantasticFour'':
** Volume 1 Issue #10. Doctor Doom develops a shrink ray device with the intent of using it on the ComicBook/FantasticFour, but he ends up getting HoistByHisOwnPetard and shrunk down to nothingness.
** Volume 3 Issue #65. Using Doctor Doom's shrink ray device, Reed Richards shrinks ComicBook/TheThing down to half size so he can [[AirVentPassageway travel through the Baxter Building's ventilation ducts]] in search of intruders.
** Fantomex apparently stole this shrink ray and uses it in ''ComicBook/UncannyXForce'' to shrink the physical exterior of a kind of pocket dimension called The World for easier transport and storage.

* In ''ComicBook/AmericaVsTheJusticeSociety'', the Brainwave subjects eight members of the ComicBook/JusticeSocietyOfAmerica to one so he can hold them hostage.
* ''ComicBook/DarkHorseMonsters'': The protagonist of "Jungle of the Giants!" is shrunk and put in a terrarium by his own son using a shrink ray.
* In ''ComicBook/TheScrameustache'', Renaud, a small-sized human, gives a shrink ray weapon to Khena. When the duo were confronted by Kromoks, Renaud yelled at Khena to shoot. Khena fumbled, not knowing how to operate the weapon. One Kromok suggested pressing the red button which Khena did, shrinking down the foolish Kromok.

* In the ninth chapter of ''Fanfic/TheMysteriesOfTheLoudHouse'', a group of otters is reduced by a shrink weapon.
* ''Fanfic/{{Metro}}'': In ''Fall Rush'', they're mentioned:

[[folder:Films -- Animated]]

[[folder:Films -- Live-Action]]

* ''Film/FantasticVoyage'' features a submarine crewed by surgeons which is sent into a scientist's brain to destroy a blood clot from the inside.

* ''[[http://en.wikipedia.org/wiki/Attack_of_the_Puppet_People Attack of the Puppet People]]'': The puppet people don't actually attack. They've been shrunk by a puppeteer.
* ''Film/OnceUponASpy'': The BigBad has a device that can fire a beam that shrinks large objects (like an aircraft carrier) down to the size of toys. He ends up being shrunk by his own device.
* Not a ray, but ''Film/TheDevilDoll'' featured a shrinkage-inducing chemical process that reduced people or animals to the size of toys. Could be the UrExample, from 1936.
* Dr. Thorkel has one in ''Film/DrCyclops''. It's basically a big silver ray gun thing he keeps locked inside of a room in his lab. Anything inside the room when it's activated gets shrunk.
* ''Film/{{Downsizing}}'' has this as the "miracle cure" for overpopulation and to save the environment as having smaller people means using less resources and having more space.
* ''Film/AntMan1''. The BigBad hasn't perfected the technology to successfully shrink a person and survive the process, so he uses a handgun-like prototype to commit murder and dispose of the body, now a small puddle of LudicrousGibs which he flushes down the toilet. Ant-Man also has throwing disc devices that can shrink or expand inanimate objects, which he uses as {{Improvised Weapon}}s.
* In ''Film/OnceUponASpy'', BigBad Marcus Valorium's plan for world domination centres around his new invention: a cosmic ray powered molecular condenser. Or, to put it another way, a giant shrink ray.

* ''Literature/TheStainlessSteelRat For President'' has Jim diGriz and his team carry items of miniaturised equipment thanks to a molecular extractor which can remove 99% of their molecules, then restore them to full size by extracting molecules from the surrounding area. Features only the "mass change" item above.
* ''Literature/TheSizeSpies'' by Jan Needle features a shrink ray created by an eccentric inventor, then stolen from its inventor.

* The Television-Chocolate setup in ''Literature/CharlieAndTheChocolateFactory'' involves one. Because the image of an object on television is always smaller than the actual object, teleporting an actual object by television requires the object in question to be much larger than it ordinarily would be -- the result is that a chocolate bar the size of mattress comes out on the other end as no bigger than a regular chocolate bar. When Mike Teavee decides to try the system on himself, he winds up small enough to fit in the palm of his mother's hand. Since this ray's effects are permanent by design, Mike has to be stretched out to restore him to anything close to his original height (and winds up quite a bit taller than that).
* The novel ''Literature/{{Micro}}'', by Creator/MichaelCrichton, involves one, and is a rare modern example of this trope that is neither a comedy nor aimed at children.
* In ''Literature/TheMagicSchoolBus'', a shrinking ray is one of the bus' many features. There is also a portable version called, appropriately enough, the "Porta-Shrinker".
* In ''Literature/TheLastDaysOfKrypton'', Brainiac uses one to reduce the City of Kandor to convenient portable size. He's done this many times before.

** In the [[UsefulNotes/TheSilverAgeOfComicBooks Silver]] and [[UsefulNotes/TheBronzeAgeOfComicBooks Bonze Ages]], Superman had one that could be used to allow people to enter the Bottle-City of Kandor (which was originally shrunk by Brainiac using a shrink ray). Notably, Superman's shrink ray worked by exchanging one full-size person for one shrunken Kandorian, making them swap sizes. It was many years before he could find a way to enlarge all of Kandor on its own, and permanently, in ''Superman #338: "ComicBook/LetMyPeopleGrow"''.

* The Dada aliens[[note]]Yes they're based on ''that'' UsefulNotes/{{Dada}}[[/note]] from ''Series/{{Ultraman}}'' (and a number of subsequent ''Franchise/UltraSeries'') are famous for using these to capture humans and take them back home to be used as scientific guinea pigs.

* In the UsefulNotes/ZXSpectrum game ''The Incredible Shrinking Fireman'', the titular character, whilst fighting a blaze at a factory, accidentally gets zapped by a shrink ray and must find a way to expand back to full size.

** ''VideoGame/PlantsVsZombies'': The UsefulNotes/NintendoDS trailer for the game has [[BigBad Dr. Zomboss]] use this to shrink his zombies, which explains the Small Zombie Big Trouble minigame. Ironically, you cannot play that minigame on the DS.

** As ''VideoGame/SonicMania'' is a love letter to the games from the [[UsefulNotes/SegaGenesis Genesis]] era, Metallic Madness Zone and its shrink rays return in that game. The boss of Act 2 is fought when Sonic and/or his friends are tiny.

[[folder:Web Original]]

* Creator/HannaBarbera
** In ''Micro Ventures'', a segment on ''WesternAnimation/TheBananaSplits'' show, Professor Carter and his two teenagers use a shrinking machine to reduce themselves and their dune buggy to miniature size and explore a MouseWorld.
** ''WesternAnimation/{{Superfriends}} 1973''/74 episode "Gulliver's Gigantic Goof''. The villain Dr. Hiram Gulliver uses a shrinking ray on the Superfriends to reduce them to a tiny size.

** ''WesternAnimation/Birdman1967''
*** Episode "The Ant Ape". Dr. Claw tries to use his Ultra Diminishing Ray pistol on Birdman but hits the Ant Ape instead.
*** Episode "Meets Reducto". The title villain creates a Reduction Machine with an attached pistol. Any creature or object it is fired at is reduced it to tiny size.

* ''WesternAnimation/TheSimpsons'': In the "[[Recap/TheSimpsonsS8E1TreehouseOfHorrorVII Treehouse of Horror VII]]" story "The Genesis Tub", the [[{{Lilliputians}} tiny people]] grown by Lisa make a "[[PerfectlyCromulentWord debigulator]]" which shrinks Lisa down to their size so that she can visit their world. Their world's version of [[MadScientist Professor Frink]] finds the concept of a "rebigulator" to be ridiculous.
* In ''WesternAnimation/ThePenguinsOfMadagascar'', Kowalski mentions that they are 700 years from perfecting a shrink ray (712 after Skipper destroys the prototype). In a later episode, Kowalski has a working shrink ray, but although the results are shown, [[InformedAbility you never actually see him use it]].
* Naturally, Dexter of ''WesternAnimation/DextersLaboratory'' has one, and in one occasion he uses it to shrink himself and spy on Dee Dee (but with the side effect of gradually altering his perception of reality.)
* ''WesternAnimation/PhineasAndFerb'' do this twice. Once shrinking themselves in a submarine that ends up in Candace, and again later shrinking along with friends to play hide and seek inside.
** Within the same show, some of Doofenshmirtz's schemes fall into this trope: the Shrinkspheria, which is a giant metal sphere that broadcasts shrinking ray particles upon specific objects Doofenshmirtz has animosity towards; and his old Shrink-inator, which he turned into a plant display without unplugging first.
* ''WesternAnimation/SpongeBobSquarePants'' featured the shrink ray twice:
** In "[[Recap/SpongeBobSquarePantsS2E11MermaidManAndBarnacleBoySquirrelJokes Mermaidman and Barnacle Boy III]]", when [=SpongeBob=] accidentally comes into possession of Mermaidman's UtilityBelt and, being his biggest fanboy, can't resist playing with it. Panicking over getting caught betraying Mermaidman's trust in such a way, he uses it to shrink Squidward, Patrick, Sandy, and ''everyone else in Bikini Bottom'' ([[ComicallyMissingThePoint Mermaidman included]]) to hide the truth, only to find he can't reverse it. His solution is to just shrink the town along with himself, so everything is relatively the same size as before (except Plankton).
** "[[Recap/SpongeBobSquarePantsS4E15SquidtasticVoyageThatsNoLady Squidtastic Voyage]]" has a FantasticVoyagePlot involving Squidward swallowing his reed.

* ''WesternAnimation/TheVentureBros'': Rusty Venture has a junky shrink ray gun that makes an occasional appearance. There's something rattling inside of it and the logo on its handle is a picture of the gun itself rather than a visual representation of shrinking. In "Tag Sale, You're It!" Billy and Pete try to buy it, but their jokes at its expense cause Rusty to refuse the sale. It next appears MagicVersusScience competition between Dr. Venture and Dr. Orpheus to see who could successfully shrink someone. (They both fail.) In another episode, it's used to shrink SPHINX's submarine so it could be used in a FantasticVoyagePlot.

* In the Creator/CartoonNetwork Groovies episode "Dee Dee and Dexter" (''WesternAnimation/DextersLaboratory'' anime style), Dexter uses a pistol-like device to shrink Dee Dee.
* One is used on ''WesternAnimation/TheHerculoids'' in the episode "Tiny World Of Terror."
* This is Reducto's villain schtick in ''WesternAnimation/HarveyBirdmanAttorneyAtLaw''.

* ''Gilligan's Planet'' had an episode where Gilligan discovered an alien size-changing machine shaped like a [[RubiksCube Rubik's Cube,]] that only operated when the puzzle was solved. Three guesses [[TheEighties when this episode was made.]]
* The ''WesternAnimation/StarTrekTheAnimatedSeries'' episode "[[Recap/StarTrekTheAnimatedSeriesS1E11TheTerratinIncident The Terratin Incident]]" has the ''Enterprise'' crew mysteriously shrinking. It eventually turns out that a tiny, shrunken city on the planet below wanted to attract their attention for help, and could only doing so by subjecting them to the same [[AppliedPhlebotinum Phlebotinum]] that shrank them.
* The ''WesternAnimation/ZulaPatrol'' episode about microscopes has the heroes shrunk down by the inhabitants of an "itty bitty city'' in a discarded pizza box. They just wanted to let the heroes know they were there, for fear they would unknowingly throw out the pizza box and destroy their city.
* The classic ''WesternAnimation/SpiderMan1967'' cartoon series had an episode where the title villain, the "Fifth Avenue Phantom" has robots disguised as mannequins planted in fancy department stores where after hours they are activated, shoot shrink rays from their eyes reducing furniture down to down size in order to smuggle them out to his secret warehouse where they would be converted back to their original size to be sold illegally. Eventually, when Spider-Man catches up to him, the Phantom tries to have his robots use their shrink rays on him, but the hero manages to dodge the rays long enough to overpower the Phantom, seize his control box and deactivate them.
* ''WesternAnimation/TheTransformers'' had the episode "Microbots," which revolved around Bumblebee, Perceptor, and Brawn shrinking down to enter Megatron's body and remove a power enhancing crystal.

* In the ''WesternAnimation/DefendersOfTheEarth'' episode "Bits 'n' Chips", Rick invents a "micronizer", a ray gun which can shrink objects to near microscopic size. However, the effect only lasts for a hour, after which the object returns to its normal size. Though it does provide Rick (along with LJ, Jedda and Jedda's panther, Kisa) with a means of getting inside Dynak-X and defeating the electronic maggot which Ming has used to corrupt her.
* ''WesternAnimation/JuliusJr'' has the Shrinkerator, a machine that can be used to shrink items down to minuscule sizes.
* ''WesternAnimation/ThreeTwoOnePenguins'' has the galeezel, which is used to bring Jason and/or Michelle aboard the toy-sized Rockhopper.
* ''WesternAnimation/MegaManRubySpears'' had an episode aptly titled "The Incredible Shrinking Mega Man" that used these. Wily's plan involved using a large shrink ray to shrink whole cities and sell them to wealthy criminals.
* One episode of ''WesternAnimation/TheRealGhostbusters'' has the Ghostmaster sending ghost bounty hunters to capture them. One of the ghost make them small in order to trap them easier and HilarityEnsues.
* Almost all episodes featuring the Fmeks in ''WesternAnimation/MenInBlackTheSeries'' would include some sort of size-changing AppliedPhlebotinum as the Fmeks are very small. In one episode Jay is made small in order to [[ItMakesSenseInContext fight them easier]] and in other the opposite happens; a Fmek and one of the Worms is increase to {{Kaiju}}-size.
* In the ''WesternAnimation/ReadyJetGo'' episode "Jet Shrinks the Kids", Jet builds a shrink ray so he, Sean, Sydney, and Sunspot can become small like Mindy. It can also be used as a grow ray when reversed.

* In the ''WesternAnimation/DennisTheMenace'' episode, "The Incredible Shrinking Dennis", [=PeeBee=] invents a shrink ray called the Shrinkerciser, which he uses to shrink Henry's bowling ball. When Dennis kicks the Shrinkerciser out of anger, it shrinks him. While in his shrunken state, Dennis has to avoid being eaten by Hot Dog, his pet cat, until [=PeeBee=] comes back with an antidote.
* This trope shows up more than once in the ''Franchise/LiloAndStitch'' franchise.
** ''WesternAnimation/LiloAndStitchTheSeries'' has Jumba create two different shrink rays that are used for both shrinking and enlarging in separate episodes.
*** In "[[Recap/LiloAndStitchTheSeriesS1E32Poxy Poxy]]", Jumba uses a "reducer ray" on Lilo and Stitch in the X-Buggy so the human-alien duo can capture a microscopic [[Characters/LiloAndStitchExperiments experiment]] that causes illness ([[Characters/LiloAndStitchExperiments2Series X-222/Poxy]]) from within Pleakley.
*** In "[[Recap/LiloAndStitchTheSeriesS1E29ShortStuff Short Stuff]]", Stitch uses a "Protoplasmic Growth Ray" so he can become big enough to ride a roller coaster, but accidentally goes too far and becomes too big. It becomes more difficult for him to move in his newfound giant size, and not only that but [[MonsterOfTheWeek the episode's experiment]] ([[Characters/LiloAndStitchExperiments2Series X-297]]/[[SpellMyNameWithAnS Shortstuff]]) also gets mistakenly enlarged and defeats Stitch in battle. Stitch is eventually returned to his normal small size to fight back and stop the experiment, who is then given a "one true place" that is based on one of his abilities and his new large size. Additionally, Gantu uses the shrink ray on X-625/Reuben to try to fight back against Stitch and his ''ʻohana'', but the lazy experiment simply ignores them in favor of eating the world's largest sandwich.
** The finale film ''WesternAnimation/LeroyAndStitch'' reveals that Jumba also created a ''living'' shrink ray in the form of his very first experiment, [[Characters/LiloAndStitchExperiments0Series X-001/Shrink]], whose ability is shown via newspaper clippings that shows that he once enlarged Jumba's then-partner Dr. Hämsterviel to a giant. However, it wouldn't be until the ''Anime/{{Stitch}}'' anime that we see him using his abilities in action.
*** "Shrink" has him shrinking the main characters down to a small size, although not to microscopic levels like in "Poxy" of ''The Series''. The episode ends with the characters back to their regular sizes, and him enlarging the alien [=BooGoo=] to become bigger than the Earth.
*** "Experiment-a-palooza" has him enlarging Stitch to become a giant. Not only that, because [[Characters/LiloAndStitchExperiments2Series X-210/Retro's]] abilities were also used on Stitch, the blue experiment is also reverted to his original programming and goes on a rampage.
* ''WesternAnimation/DanVs'': Elise invents a shrink ray. [[spoiler: Dan ends up using it to shrink her and his nemesis: Gigundo Mart.]]
* In one episode of ''WesternAnimation/TimonAndPumbaa'', the pair try to get past a stubborn goat blocking the border into France. One of their attempts is to shrink down and slip underneath it. Unfortunately, the effect wears off too fast and they end up returning to normal size right under the goat.
* ''WesternAnimation/{{Noveltoons}}'': In ''Out of This Whirl'' a Martian spends the day with an Earth family. When a traffic cop attempts to write his host mother a speeding ticket, the Martian uses his ray gun to shrink the bothersome officer down to the size of a mouse. The woman and Martian then drive away leaving the [[IncredibleShrinkingMan miniaturized patrolman]] still perched high up on his motorcycle as he yells after them in a [[ResizedVocals high-pitched voice.]]

* ''WesternAnimation/TheVentureBrothers'': Rusty Venture has a junky shrink ray gun that makes an occasional appearance. There's something rattling inside of it and the logo on its handle is a picture of the gun itself rather than a visual representation of shrinking. In "Tag Sale, You're It!" Billy and Pete try to buy it, but their jokes at its expense cause Rusty to refuse the sale. It next appears MagicVersusScience competition between Dr. Venture and Dr. Orpheus to see who could successfully shrink someone. (They both fail.) In another episode, it's used to shrink SPHINX's submarine so it could be used in a FantasticVoyagePlot.

* ''WesternAnimation/DespicableMe'' has Gru plotting to use a shrink ray to steal the moon. [[spoiler:Not only are the effects temporary, but as Dr. Nefario discovers, their duration is inversely proportionate to the subject's original mass (i.e., the bigger the object, the faster it takes before it starts to grow back to normal). Nefario considers naming this principle after himself.]]

* One of the recurring gadgets in ''Manga/{{Doraemon}}'' is a "Small Light". A flashlight-like shrink ray which shrinks any object and person down and does wear out eventually as seen in one movie. There's also a "Big Light" which does the opposite. The small light getting stolen in ''Anime/DoraemonNobitasLittleSpaceWar'' even forms a plot point for the gang are stranded finger-sized most of the film until they can retrieve it.

* ''Once Upon a Spy'': The BigBad has a device that can fire a beam that shrinks large objects (like an aircraft carrier) down to the size of toys. He ends up being shrunk by his own device.

* Seen twice so far in the ''Series/{{Arrowverse}}'':
** In ''Series/LegendsOfTomorrow'', [[SizeShifter Ray]] creates a device that can shrink and expand objects, although the effects are temporary, and the expanding feature was just in case they didn't want to wait for the shrinking to wear off.

* ''Series/{{The Avengers|1960s}}'' episode "Mission... Highly Improbable" has a device that sends out a ray that shrinks objects or people down to the size of toys.
* ''Series/BlakesSeven''. In "Gambit", Avon and Vila smuggle Orac inside a casino for some gratuitous cheating by using 'molecular reduction'. In this case no ray is used; the MagicalComputer simply does this to himself.

** TheMaster is armed in many of his appearances with a ray gun called the Tissue Compression Eliminator, which simultaneously kills the target and shrinks the corpse down to a convenient-to-dispose-of size. It kept the rule about shrunk objects having less mass, but mostly averted the one about living creatures surviving the process. The novelizations explicitly state at one point that the death is due to realistic SquareCubeLaw effects. The one case where a person miniaturized by the TCE survives is when [[spoiler:TheMaster accidentally miniaturizes himself]]. Two characters in the ''Magazine/DoctorWhoMagazine'' comic strip have survived the Tissue Compression Eliminator, ComicBook/DeathsHead presumably because he is a robot and less subject to SquareCubeLaw (later sources would suggest he'd been artificially enlarged, and the TCE merely restored his "natural" size), and Izzy for unknown reasons. [[spoiler:The TCE made its new series debut in [[Recap/DoctorWhoS38E1E2Spyfall "Spyfall"]].]]
** [[Recap/DoctorWhoS15E2TheInvisibleEnemy "The Invisible Enemy"]] includes a FantasticVoyagePlot (using a shrink ray based on the same technology as lets the TARDIS be bigger on the inside, allowing a bit of handwaving about the issues of shrinking living things).

** [[Recap/DoctorWhoS32E8LetsKillHitler "Let's Kill Hitler"]] lampshades it: The episode features a robot that can shrink people and transport them inside itself. When Amy and Rory are captured, Rory explains that they were hit by a "miniaturisation ray" because "Well, there was a ray, and then we were miniaturized."

** In "Bone to Be Wild", the villainous Br'Nee shrinks Zhaan in order to vivisect her.
** Depicted in more detail in "I Shrink Therefore I Am". The crew are shrunk by {{bounty hunter}}s to make them easier to transport and control. Sikozu immediately starts listing all the reasons why this is impossible (their brains should be too simple to function, and they shouldn't be able to breathe normal-sized air molecules) until Rygel tells her to just [[MST3KMantra shut up and accept that the impossible has happened]]. The episode ends with a fight between Crichton and the VillainOfTheWeek, with each trying to shrink the other and resize themselves. Needless to say, someone ends up getting squashed nastily.

* ''WesternAnimation/TheSimpsons'': In a ''WesternAnimation/TreehouseOfHorror'' episode, the tiny people that Lisa grew made a "[[PerfectlyCromulentWord debigulator]]" which shrank Lisa down to their size so she could visit their world. Their world's version of [[MadScientist Professor Frink]] found the concept of a "rebigulator" to be ridiculous.
