->''"''This'' caused the 1977 New York blackout. A practical joke by the Great Attractor. He thought it was funny as hell."''
-->-- '''[[Film/MenInBlack Agent K]]''' (about a one-inch diameter ball)

A ball (or some other projectile) bounces around incredibly quickly in a small location and causes vast amounts of damage. HilarityEnsues.

Unlike the PinballProjectile, the trajectory of the HyperDestructiveBouncingBall is completely random and always leaves a swath of destruction in its wake. They tend to [[ArtisticLicensePhysics display unbelievable inertia]] and won't stop ricocheting unless someone/thing catches it. They also take the Law of Conservation of Momentum and throw it out the window, as it's not uncommon for one to inexplicably ''speed up'' when it hits a wall. No wonder it's generally PlayedForLaughs.

Confuse it with HappyFunBall at your peril. There's also a [[FollowTheBouncingBall safer version]] for sing-alongs. Also see BouncingBattler, when a character ''becomes'' one of these to fight foes. A ReflectingLaser can be this.



* In a '90s [[Creator/ChuckECheese Chuck E. Cheese]] ad, the narrator says, "At boring restaurants, nothing goes right." A boy pokes an absurdly large pea with his fork and accidentally causes pandemonium.

[[folder:Anime & Manga]]
* In ''Manga/RanmaOneHalf'', the detachable [[RingsOfDeath blade ring]] of the [[BladeOnAStick Kinjakan]] acts exactly like this when used in an enclosed space. [[OhCrap Like, say, a narrow cavern]].
* In ''Manga/MedakaBox'', Unzan uses superballs as his weapon. They defy the laws of physics, breaking concrete with ease. In one instance, they also deploy wires to try and detain Medaka.
* In ''LightNovel/{{Katanagatari}}'', Maniwa Pengin uses this as his weapon, since he was BornLucky enough to avoid being hit.
* In ''Manga/OnePiece'', the main character Luffy is made of rubber and one of his techniques is called Gear 4 Boundman, where he inflates his muscles, making himself look like a giant bouncy ball. He bounces repeatedly to increase his speed and destructive power, thus making him a living Hyper-Destructive Bouncing Ball.

* In an ''Franchise/ArchieComics'' story where the cast are portrayed as superheroes, Evilheart (Reggie) and Pureheart (Archie) fight a baddie who has a ring that causes objects to rapidly degrade. Every weapon they fire at him, he simply destroys. To get the better of him, Evilheart tosses out a little black ball, which bounces all over the room. Because it is so quick, the villain can't hit it, and eventually his weapon runs out of juice. However, in trying to destroy the ball, the villain also destroys all his loot -- which means it can't be returned to the victims, forcing Evilheart to pay reparations.
* ''ComicBook/GastonLagaffe'':
** This comes up on three occasions: once when Gaston throws around a ''superballe'' and it bounces crazily until his office is devastated (and Fantasio swallows it); once when his cat tries to grab it and goes into a frenzy; and once again when he plays jokari with it.
** He also once makes a kangaroo ball -- the kind that you sit on and bounce around -- out of the same stuff that superballes are made of. The final panel reads like he died committing this stunt -- it claims that the last person to see him was a flight attendant in a plane several miles off the ground. Thankfully for him, the NegativeContinuity kicks in.
* In ''Comicbook/AstroCity'', the Junkman has trick marbles that are attracted to a target and adhere to him. The more the target tries to dislodge, the faster he attracts them.
* ''Comicbook/JudgeDredd'':
** The miracle plastic Boing® is a spray-on substance that expands and encases the user in a very bouncy ball. It's legal to use for various games and activities (appropriately referred to as "boinging") at special facilities that cater to these interests (namely, the Palais de Boing®), but boinging outside of such facilities is very dangerous and ''highly'' illegal.
** Another Judge Dredd example is the Rubber Richochet bullets used by the Judges. Mostly used by the big JD himself to pull off "impossible" shots. Nothing hilarious about these babies. Justified in that real life rubber bullets (intended to be non-lethal) have [[http://www.ncbi.nlm.nih.gov/pubmed/16167715 killed]].
* The WesternAnimation/DonaldDuck comic [[http://coa.inducks.org/story.php?c=I+TL+2221-1 "Paperino contro i veggenti viola"]]. Donald Duck and Fethry Duck are secret agents with a collection of nifty gadgets, including one such a ball.
* The French comic ''L'Imploseur'' features one as the ultimate security system, being released inside a sealed tunnel so it would eventually go through everything human-soft, killing everyone on the team but the hero and his girl (and even then only because they found the exit in time).

[[folder:Comic Strips]]
* This happens in ''ComicStrip/FoxTrot'' when Jason hurls a superball from a lacrosse racket indoors. He also mentions having once hit a golf ball in the basement.
* A ''[[ProjectileToast piece of toast]]'' does this in ''Comicstrip/{{Garfield}}'' after Jon [[WalkingTechbane fixed the toaster]].

[[folder:Fan Works]]
* In a majority of ''Franchise/SonicTheHedgehog'' fanfiction, the titular character basically becomes one.
* In a related example, the Naruto fanfiction "[[Fanfic/YetAgain Yet Again with a Little Extra Help]]" by Thirdfang gives Choji an additional jutsu to make his body react like superpowered rubber. Pair that with Human Boulder and Needle Jizo, and the sister of the character that taught him this combo comments it to be 'bouncy spinning hedgehog style at its finest'.
* In the ''FanFic/FacingTheFutureSeries'', [[WesternAnimation/DannyPhantom Jack Fenton]] invents the "Ecto-Bondo", which fires one of these that don't stop until they hit ectoplasm. Naturally, HilarityEnsues.

[[folder:Films -- Animation]]
* In ''WesternAnimation/TheIncredibles'', the Omnidroid acts somewhat as one when it retracts its claws. It somehow can turn directions as a smooth metal sphere, and the fact that it is at least five stories tall adds to the "Destructive" bit.

[[folder:Films -- Live-Action]]
* ''Film/JingleAllTheWay'' features a ping-pong-like raffle ball doing this within a mall. Even though the movie is supposed to be a comedy of sorts, everything up until now was not this goofy and did not suspend the laws of physics this much, making this scene feel out of place. After this happens, several other very goofy scenes show up. If it weren't for the ridiculous ball, the other scenes' departure from the apparent laws of physics within the movie might have come as more of a shock.
* This happens in the remake of ''Film/{{Flubber}}'' whenever a liquid form of the titular material is sprayed on an object. Justified in that that's half the ''point'' of the substance, [[MinovskyPhysics exotic matter]] aside.
* According to ''Film/IndianaJonesAndTheLastCrusade'', this happens to bullets if they're fired inside a tank.
* In ''Film/MenInBlack'', J touches some alien device and it bounces wildly all over the headquarters until K catches it. In J's defense, [[SchmuckBait it was just floating out in the open.]]
* In ''Film/MysteryMen'', the Bowler's bowling ball (which houses the spirit of her dead father) does this when finally unleashed.
* In ''Film/{{Explorers}}'', the little force field ball that Wolfgang creates does this when his cat jumps on the keyboard, destroying half the basement.
* Not quite as hyper as most examples, but in ''Film/GodzillaFinalWars'', Anguirus can roll himself up into an armored ball of spiky death and bounce around. He uses this technique to destroy one of mankind's flying battleships.
* In ''Film/IComeInPeace'' (1990), an alien sawblade-like disk does this quite memorably, until caught (attracted?) mid-flight with a strong magnet.
* In ''Film/StrangeBrew'', bullets stuck up Bob Mckenzie's nose to staunch a nosebleed shoot around the courtroom after he fails to suppress his laughter.

* There's a [[RussianHumor Russian joke]] that goes like this:
-->The Chinese have dropped a nuclear bomb on USSR. 5 million dead, Lots of fuss in the media, statements from politicians, etc.\\
A couple days later there's another media explosion: In retaliation the Russians have dropped a rubber bomb on China. 50 million already dead. The bomb keeps bouncing.

* There's a nasty use of this in ''Literature/DiamondDogs'' by Creator/AlastairReynolds. The party are in a mysterious alien structure that requires them to solve puzzles to move from room to room. When they take too long over one of the early rooms, a small ball pops out of one wall and starts bouncing around, getting harder and faster and causing bruises, then broken bones, until it finally goes ''clean through someone's arm''. And these guys are wearing spacesuits.
* Walter Tevis' [[AbsentMindedProfessor slightly mad scientist]] Farnsworth creates a form of rubber that [[ArtisticLicensePhysics absorbs energy from its surroundings to fuel ever-increasing bounces]] in "The Big Bounce".
* In ''Literature/PeterGraves'', Houghton Furlong invents an anti-gravity alloy named Furloy, thus a ball of the stuff bounces higher with each bounce. Tragically, the bouncing ball ends up destroying his house.
* In ''Literature/HarryPotter'', Bludgers are balls enchanted so that they do this during Quidditch matches.

[[folder:Live-Action TV]]
* ''Series/Warehouse13'' featured a pair of croquet balls with this property.
** There was also a dodgeball that would duplicate itself every time it struck something, eventually resulting in a ceaseless bombardment.
** Artie also finds himself on the receiving end of a ball that bounced off his head at high speed until he caught it. Not deadly, but disorienting.
* ''Series/SaturdayNightLive'' gives us a fake toy called "Happy Fun Ball", which may suddenly accelerate to dangerous speeds.

[[folder:Music Videos]]
* In Music/TheBlackEyedPeas' video for "Pump It", Will.I.Am manages to invoke this with a ''[[UpToEleven bowling ball]]'' while fighting a thug.
** Closer inspection reveals it to be a soccer ball. No less impressive though.
* [[http://www.youtube.com/watch?v=yu99_ulxyFI "The Boxer"]] by Music/TheChemicalBrothers has this as its main focus. That thing just ''will not die''.

* Seen on the backglass of Creator/{{Capcom}}'s ''Pinball/{{Breakshot}}'', which shows a pool player bouncing the cue ball off the table, knocks a glass out of the redhead's hand, ricochets off the nose of a stuffed moose, then bounces off a brunette's behind to settle back onto the table.
* The playfield for ''Pinball/CirqusVoltaire'' has the Menagerie Ball, a rubber ball contained in a spherical cage. The player must hit the ball to Join The Cirqus, and it frequently wreaks havoc with the pinball's movement.

* In ''VideoGame/Jak3Wastelander'', there is an upgrade on one of the weapons that allows the bullets to bounce off of walls. When used outside it would usually only hit one or two walls and fly into the sky, but when used indoors and in small spaces it could cause HDBB effect (especially if you rapidly send out shot after shot, created a Multi-Hyper Destructive Bouncing Ball effect).
* The very gameplay of ''VideoGame/{{Arkanoid}}'' (and all ''VideoGame/{{Breakout}}''-derived games) is based on smashing things with a bouncing ball.
** But things get serious when the ball ''no longer'' bounces off: many games in this genre include a power-up that makes the ball smash through ''anything'' (except the edges of the screen) without deflecting or even slowing down. Often a level-ender.
* In ''VideoGame/MegaMan10'', the Rebound Striker gains more destructive power the more it bounces. Strike Man's version is ''both'' this trope and PinballProjectile- on the final bounce, his ball heads directly for Mega Man.
** In the original VideoGame/MegaManX1, Armored Armadillo did this as his standard attack. It was effectively invincible, unless you managed to [[ElementalRockPaperScissors electrocute him]], which would make his armor fall off.
** In VideoGame/MegaManX5, X acquires the "Spike Ball" after defeating Axle the Red. This weapon, in its charged up mode, fires one of these, a purple ball of spikes and vines that ricochets in a random pattern 4 times on the screen before leaving the premises. Also doubles as a SpikeBallsOfDoom.
* In ''VideoGame/{{Bully}}'', the [[InfinityPlusOneSword Rubber Band Ball]] is a soccer ball sized mass of rubber bands that flies around on a random destructive path, eventually stopping but barely losing momentum before then and [=KOing=] anyone it hits except you. You can launch multiple ones at a time. ForTheLulz, unleash them in the enclosed space of the dorms.
* Combine dark energy cores in ''VideoGame/HalfLife2'' are a rare serious interpretation. The sphere stores dark matter plasma for the Combine and is relatively safe so long as it remains confined in a storage device or generator. If released, it accelerates rapidly and smashes about before exploding; organic matter is disintegrated on contact, vaporizing the victim into thin air while floating them upwards due to their mass being canceled out by the process. Especially notable as the Combine doesn't use it merely as a portable power source but actually weaponized it as the grenade launcher-equivalent on the Pulse Rifle.
** [[http://twhl.info/competitions.php?results=20 "Orb"]], a map made for a ''VideoGame/HalfLife1'' mapping competition, is about a deadly sphere-like artifact that utterly devastates a facility while displaying all the characteristics of a HyperDestructiveBouncingBall (and showcasing the mapper's scripting prowess).
* In ''VideoGame/SuperMarioLand'', instead of gaining the power to throw [[KillItWithFire fire balls]], you get the power to throw these instead. Sadly this power never made a reappearance, along with pretty much everything in this game except Daisy.
* The Red Fireballs in ''VideoGame/MarioBros''. They start out slow; faster ones appear the longer you stay in the level.
* The "Proximity Pinball" secondary function on the Grenades in ''VideoGame/PerfectDark''. The grenade will bounce around for a good while until it comes close to a character, which, in close quarters, could easily be ''[[HoistByHisOwnPetard you]]''.
* ''VideoGame/{{Postal}} 2'' has a napalm launcher with a fire mode that shoots a bouncing napalm canister. One that spills fuel that ignites in a second. After a few seconds, it'll explode in a big puff of fire.
* Kirby's Ball ability in ''VideoGame/KirbysAdventure'' bounces slowly at first and picks up speed, then starts to glow and ricochets off of the floor and ceiling rapidly, causing some of the highest damage out of all the abilities upon contact.
* The Super Ball item in ''VideoGame/FinalFantasyVI'', which deals damage to up to four enemies during a battle, and can even hit one target multiple times occasionally.
* ''VideoGame/{{Bulletstorm}}'': The Bouncer weapon fires a large explosive cannonball which you can bounce around knocking enemies over before detonating it. You can turn this Up to Eleven with its charge shot, which causes the ball to release an explosion every time it bounces. You can kick it around to direct the blasts!
* Orianna from ''VideoGame/LeagueOfLegends'' is capable of chucking her ball around like this.
* The Soccer Ball from ''VideoGame/DeadRising'' is capable of being this in tight spaces like the elevator.
* ''Franchise/{{Castlevania}}''
** In ''VideoGame/CastlevaniaOrderOfEcclesia'', the ''Globus'' glyph sends out two bouncing balls like this. In tight spaces it can get very destructive, especially if you power up the strike attribute and keep spamming them. It's one of the easiest (and most fun) ways to destroy some of the DemonicSpiders you face in the BonusDungeon.
** ''VideoGame/CastlevaniaSymphonyOfTheNight'' also has the "Rebound Stone". In an open space it's essentially a slower knife weapon that fires at an unusual angle, but it can clear a tight hallway of weaker enemies with one shot.
* [[http://en.wikipedia.org/wiki/JezzBall JezzBall]] --from the good 'OLE [[UsefulNotes/MicrosoftWindows Windows]] Entertainment Pack-- was about damage control caused by such balls. [[ExcusePlot Or something]].
* ''VideoGame/{{Touhou}}'' has Reimu Hakurei's [[AncestralWeapon Yin Yang Orbs]]. She usually uses it as [[AttackDrone options]] that fires additional bullets when you're playing as her. But when you're ''facing'' her, expect to dodge a swarm of balls bouncing around the screen in a chaotic manner. This leads to inevitable {{DoubleEntendre}} and MemeticMutation: "I was killed by Reimu Hakurei's balls."
** In the fighting games, Yukari can use Ran and/or Chen like this.
** In ''Story of Eastern Wonderland'', Meira's final attack is to sheathe her sword and start shooting bouncing balls across the screen.
* ''VideoGame/{{Berzerk}}'' villain character Evil Otto is a bouncing ball with a smiley face.
* ''VideoGame/MetalWarriors'' features the Ballistic. A spherical mecha that can do a charge attack.
* ''VideoGame/{{Borderlands2}}'' gives us rubberized grenades, which bounce off hard surfaces and detonate on impact with enemies, elemental barrels, and possibly ''the player''. Jack help you if you have a rubberized [[RecursiveAmmo Bonus Package]] grenade mod and you try to use it in an enclosed space.
* The ''Franchise/RatchetAndClank'' series has the Bouncer weapon, a gun which shoots out a large bomb that, once it explodes, dispenses even more bomblets. Leveling it up increases the size and power of all the involved bombs, and they have a slight homing property as well.
* This is your weapon (other than crushing monsters with apples) in ''VideoGame/MrDo''. Especially useful because the game taken place in narrow corridors dug out by your hero, thus usually allowing you to predict the trajectory. However, you only have one "Power Ball" at your disposal and must go and retrieve it if it fails to hit a monsters.
* In ''Algodoo'' (a physics simulation game), any object with restitution cranked up way too high will end up being this, before clipping through whatever it hits due to flying around at ludicrous speeds, and going into space, never to be seen again.

* In ''Webcomic/TheOrderOfTheStick'', Xykon casts Symbol of Insanity on a superball and tosses it into a group of paladins, creating a HatePlague that causes them to slaughter each other (hey, it's a ConflictBall!). The damage is not done by the ball itself, which behaves like any bouncy ball, but from the spell cast on it.
* Gregory pulls off an version of this in ''Webcomic/DominicDeegan''. Gregory is the only defense against [[ZergRush an army]] of ChaoticEvil cultists. Being the [[TechnicalPacifist pure-hearted]] WhiteMage, he cast a spell on a bouncy ball and lets it fly. He apparently also did the same to Dominic's crystal ball in his youth.

* The Wiki/SCPFoundation has [[http://scp-wiki.wikidot.com/scp-018 SCP-018]], a 6cm red ball that, in a standing affront to the laws of thermodynamics, can bounce with 200% efficiency. A normal bouncing ball put through [[http://scp-wiki.wikidot.com/scp-914 SCP-914]] on "Fine" and "Very Fine" settings ''thrice'' also has this property. The former caused 5 civilian injuries and is currently sitting in a tank of goo, while the latter caused 45 casualties upon being dropped and is currently thought to be orbiting Mars.
* Played for laughs in this well-made [[http://www.youtube.com/watch?v=qe3e5kmtduc Doctor Who video]], in which a rock tossed aside by the 5th Doctor bounces around the Doctor Who universe causing mayhem.
* In ''Machinima/RedVsBlue'', Agent North Dakota traps the Insurrectionist Sniper and his mooks under a BeehiveBarrier dome. The Sniper warns his men not to try to shoot it. [[TooDumbToLive One of his men doesn't listen]]. The bullet bounces all over the place and kills them all.
* It is the plot of WebVideo/CorridorDigital's ''[[https://www.youtube.com/watch?v=_0DAeQuf_0I Ballin' Out Of Control]]'', the originality of it being the fact that it is shot from the [[POVCam point of view]] of the ball.

* One of the Toyman's weapons in ''WesternAnimation/SupermanTheAnimatedSeries'' was a substance that bounces faster the longer it bounces. The idea is that eventually it'll become fast enough that the impact'll break bones. When he uses it on some of Intergang's goons, the ball is ''denting'' their armored car by the time Superman arrives. [[FridgeLogic No explanation is given as to why it didn't rip right through the thin metal roof or walls of the warehouse, even if it never happened to hit one of the windows.]]
* In the ''WesternAnimation/DarkwingDuck'' episode "Smarter Than a Speeding Bullet," the evil agency F.O.W.L. invents the "Fowl Ball" (cue groaning) -- a giant, remote-controlled ball that bounces around and smashes everything it lands on.
* In the ''WesternAnimation/FostersHomeForImaginaryFriends'' episode "The Big Leblooski", this happens with a bowling ball, to show how bad Mac is at bowling.
* Same thing happened to Ed Bighead in ''WesternAnimation/RockosModernLife''. The only thing left standing after that were the bowling pins on Ed's lane.
* In ''WesternAnimation/{{Recess}}'', Gretchen once made a material that could bounce cartoonishly ridiculous amounts no matter how you drop it, and the kids made a kickball out of it to have Vince kick when he was in a rut. Gus lost it, and when Ms. Finster found, she threw it into the sports shed, causing ''all'' the balls to start bouncing like this.
* The power of Bouncing Boy from the cartoon adaption of ''WesternAnimation/{{Legion Of Super Heroes}}'' was that he could use himself as a HyperDestructiveBouncingBall.
* When ''WesternAnimation/{{Ben 10}}'' changes into Cannonbolt, he can ''become'' one of these. Saves the day in [[http://ben10.wikia.com/wiki/The_Big_Tick The Big Tick]].
* in an episode of ''WesternAnimation/AmericanDad'', Steve Smith learns how to become a lucid dreamer by using a bouncing red ball in his dreams, to remind him he is dreaming and the dream can therefore by whatever he wants it to be. Being a teenage boy, he uses this for sex and revenge dreams often set in the school that derides him for being a nerd. When he refuses to teach the technique to Hayley and Klaus, they take revenge by bouncing a red ball at his feet while he is fully awake. Believing he is dreaming, he drives to school (causing traffic chaos and pile-ups)while wearing only his underpants, punches a teacher, sexuallymolests a cheerleader, and leaps out of the window with her believing they can fly...
* In one episode of the French CGI show ''Grabouillon'', the titular dog finds his old bouncy ball in the attic and immediately throws it, knocking himself out. He gets up and throws it again but it is even more chaotic and destructive. He and is friends try to get rid of it but the ball turns into an angry AnimateInanimateObject and attacks them. They manage to lock it up in a chest, but it grows big and bursts out, followed by several other small ones. The balls are about to end the heroes... turns out it was AllJustADream after Grabouillon was K.-O.
* Happens in one episode of ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' It's definitely one of Pinkie Pie's weirder moments. Upon getting nervous she becomes the titular object, bounces repeatedly around the room and smashes a hole in the wall.

* As mentioned in the ''Indiana Jones'' entry above, a bullet fired inside a tank will act like this. Obviously, the bullet will slow down quickly due to energy loss on the rebounds and passing through softer objects. It's still a very bad thing.
** Or, more likely, shatter on the very first impact and shower anyone near with shrapnel. Not much better.
** ''Series/{{Mythbusters}}'' demonstrated that if you're bouncing the bullet off anything soft enough that it won't shatter on the first impact, by the third ricochet, it's moving so slowly that it would merely be annoying if it hit you.
** Of course, of some primary concern is the fact that the "softer objects" inside an armored vehicle often includes the crew, and the very cramped conditions inside said vehicles...
** RealLife [[http://en.wikipedia.org/wiki/7.92mm_DS 7.92x107mm ammo]] devised by the [[UsefulNotes/PolesWithPoleaxes Polish Army]] just before UsefulNotes/WorldWarII was designed for this: flatten upon impact to light armor used in tanks of the time and spall one or more chunks of armor off the inside to ricochet around and [[{{Squick}} cut the crew to pieces]]. It was very efficient against the thin, 15-20mm or so armor of early World War II tanks, but after 1943 it became obsolete. More recently, anti-tank ammo using the same principle has come back into vogue.
** The M3 tank produced by the US as an interim measure until the M4 was ready for production had a serious flaw: its armor was riveted together rather than cast or welded. A hit by an armor-piercing round that didn't penetrate, or a sufficiently strong explosion near the tank, would cause the rivets to pop out, bounce around, and massacre the crew. One nickname for the tank was "a coffin for six/seven brothers" (different versions had different numbers of crew members).
%% * Various mobs have a method of execution which employs this principle. If you shoot someone behind the ear with a low caliber bullet, it will bounce around inside their skull eating it up like VideoGame/PacMan. It has been inspired by the hunting practice of firing low caliber bullets, like .22LR or .17HMR, at very high velocities against small game with precious furs, to kill without an exit wound and avoid staining of the fur with blood.
%%** Allegedly. In actuality they tend to simply enter the brain and stay there, a lack of an exit wound making them less messy. People are literally empty-headed, after all.
* The US has developed a device called the Kinetic Fireball Incendiary that is basically this trope. As Website/{{Cracked}} puts it:
--> "The idea is to launch lots of hollow balls of rubberized rocket fuel with a hole in one side, and light them on fire.. They become rocket-powered fireballs that bounce around inside the building, killing everything near them in the most cartoonish yet horrifying way possible. The thing is, the flaming balls don't actually have to hit you. The concept works something like a martini shaker; the reason the shaker cools your delicious drink faster than simply mixing in ice cubes is because they move around the liquid inside, cooling a higher volume in a much shorter time. With the KFI, you get essentially the same thing, except the ice cubes are flaming balls that raise the ambient air temperature to over 1000 degrees in seconds, not to mention knocking down doors and spreading the same horror throughout the building."
* The criticism made by many a ConspiracyTheorist of the theory that a single bullet [[WhoShotJFK killed John F. Kennedy]] and wounded one of the passengers in the car he was riding in. They claim that in order to cause all of the wounds it did, this bullet would've have to act like a HyperDestructiveBouncingBall, earning it the derisive name "the magic bullet". Of course, [[TakeAThirdOption there are other theories]], such as that Lee Harvey Oswald simply fired more than one bullet (difficult but possible for a [[ColdSniper trained marksman]], which he was), [[TheDogWasTheMastermind or that there was another shooter who was never found]].
** Or a more recent theory of the car being modified so the second victim was seated off to one side in front of JFK, allowing a straight-line shot for the bullet.
* Anyone who has owned a toy bouncy ball (also known as a ''Super Ball'') knows why you shouldn't let children play with them in the house. These innocuous little rubber balls are so elastic that they barely slow down at all when they bounce. It's only a matter of time before one of the little geniuses throws it against the floor as hard as he can, and it's going to ricochet off of every surface in the house until it inevitably breaks something.
