A SubTrope of HollywoodDensity, common in cartoons, characters will inflate a balloon (or another person) with his breath and automatically it starts to float. A bubblegum-based variant exists.

See also {{Balloonacy}} for when the same balloons, inflated with human breath, actually can lift something else up. Related to RuleOfFunny, TheyJustDidntCare, and CriticalResearchFailure.

[[folder: Advertising ]]

* There was a ''very'' old [=McDonald=]'s ad where Ronald inflates ''his clothes'' (apparently a jumpsuit) with lung power in order to fly.
* A commercial for a Clinique skin care product has a ''water balloon'' floating.

* The title character of ''KuangKuang'' can blow into a condom to make it float like a helium balloon.

[[/folder]]

[[folder: Film ]]

* Happened in ''WesternAnimation/{{Shrek}}'', where Shrek and Fiona inflated a frog and a snake, respectively, that then floated like helium ballons.
* In {{Disney}}'s ''Disney/RobinHood'', [[RuleOfFunny Sir Hiss inflates a balloon (from the inside!) and is able to zoom around like a helicopter using his tail as a propeller]].
* Mr. Big from ''Film/LiveAndLetDie'' is [[BalloonBelly blown up with compressed air]] and floats up to the ceiling before [[PopGoesTheHuman exploding.]]

[[folder: Literature ]]

* In the first ''Literature/WinnieThePooh'' story, Pooh uses a balloon to pretend to be a cloud. I'm not sure whether it was already inflated (in which case it could be filled with helium) or whether it got inflated via lung power during the course of the story.
** It's not 100% clear, possibly because this story is very specifically being told by Creator/AAMilne to Christopher Robin (with interruptions and such): on the one hand, Christopher Robin had brought it home from a party; on the other hand, the illustration shows him blowing it up and the text also says "and when the balloon was blown up as big as big". It's also notable that the balloon conveniently rises so it's exactly level with the top of the tree.
** In the Russian animated version, it's definitely inflated by lungpower. What's more, Piglet tries inflating it first, and only succeeds in inflating ''himself'' -- and nearly floats away before Pooh catches him.
** One episode of ''WesternAnimation/TheNewAdventuresOfWinnieThePooh'', "Balloonatics", had a balloon that Christopher Robin described as being "made of rubber and air" but was capable of carrying Pooh just like in the book. Later, Christopher reinflates it with his breath and it is buoyant enough to carry not just Pooh, but the other animals who grabbed on to try to bring him back down (except Tigger, who clearly wanted to go along for the ride).
* Subverted in one ''EncyclopediaBrown'' story. A witness claimed he saw a man known for handing out balloons abducting a child when one of his trademark balloons flew into a tree and got stuck. The witness said he climbed the tree to retrieve it when he saw the balloon man put the kid in his car and drive off. Encyclopedia deduced the witness was lying because the aforementioned balloon man always inflated his balloons by mouth, and therefore would not have flown.

[[folder: Live Action TV ]]

* ''Series/MontyPythonsFlyingCircus'': Both averted and played straight in the "Golden Age of Ballooning" episode. When Barry Zeppelin blows up balloons, they immediately fall to the ground when he releases them. However, when he tries to blow up a large balloon, the air rushes back into his body and inflates ''him'', and he floats away.
* Played with in ''AreYouBeingServed'': Mrs Slocombe is accused of being drunk, and she's asked to blow into a breathalyzer balloon. She does so and the balloon floats away.

[[folder: Music Videos ]]

* Music/TheKillers inflate and release balloons in the video for "Read My Mind". Mocked in the literal video version. "How'd we make these fly?"

[[/folder]]

[[folder: Newspaper Comics ]]

* ComicStrip/{{Garfield}} once caused "the world's largest balloon" to [[http://www.garfield.com/comics/vault.html?yr=1987&addr=870503 float the house away]].

[[/folder]]

[[folder: Video Games ]]

* ''VideoGame/WarioLand 4'': Aerodent, the aerial rodent, blows up its own teddy-bear balloon.
* In ''DonkeyKong64'', Lanky Kong can "inflate himself just like a balloon" to float himself places once he buys the potion.
* ''{{Kirby}}'' can inflate himself to fly around as one of his standard abilities, though some games limit this flight by how long he can hold his breath. [[FriendlyEnemy King Dedede]] can pull this trick as well, though it's a little harder to justify a [[{{Acrofatic}} fat blue penguin]] flying than a little, pink ball creature.

[[folder: Western Animation ]]

* ''WesternAnimation/LooneyTunes'' used this frequently. As did ''WesternAnimation/TomAndJerry''.
** Semi-averted when Wile E. Coyote is blowing up a large balloon to use as a lighter-than-air device. The air rushes back out and inflates him, but he merely bounces along the ground. (He does get airborne when, hanging onto a large bomb for ballast, he suddenly expels all his air and flies around madly like a deflating balloon.)
* The [[TheGoldenAgeOfAnimation Golden Age]] [[GenreThrowBack throwback]] ''Film/WhoFramedRogerRabbit'' does this in the opening cartoon with Roger himself.
* In the Soviet cartoons about ''Winnie-the-Pooh'', the balloon was already inflated, but then Pooh blows even more air into it to make it bigger and only then he manages to fly up with it. Fun.
* In ''WesternAnimation/TinyToonAdventures'', [[NoCelebritiesWereHarmed Orson Whales]] gave a lecture on this after an inflation scene, [[DiscussedTrope pointing out]] that "any old gas will do" for making an object float in cartoons. He also said that a can of baked beans would've been funnier.
* In at least two episodes of ''WesternAnimation/WackyRaces'', Dick Dastardly's schemes involved these kinds of balloons. One was an inflatable version of the Mean Machine, which Dastardly inflated from ''inside'' once it got large enough. An exception occurs in "The Baja-Ha-Ha Race", where Dastardly and Muttley use inflatable cows and bulls as a roadblock.
* ''WesternAnimation/ThePerilsOfPenelopePitstop'' episode "London Town Treachery": After Penelope is kidnapped, Pockets blows up a balloon with his breath and it floats up into the air for use as an observation balloon.
* Happens in the second season credits for ''WesternAnimation/{{Jimmy Two-Shoes}}''.
* Happens in ''WesternAnimation/PeppaPig'' in the episode ''Mummy Pig's Birthday''.
* In an episode of ''WesternAnimation/CliffordTheBigRedDog'', Clifford inflates a balloon, which floats.
* An episode of the ''ComicStrip/BeetleBailey'' cartoon had Sgt. Snorkel eat so much that he got a literal BalloonBelly and floated away. Makes even less sense than normal examples of this trope, as he's stuffed with ''food'', not air.
* Subverted in an episode of ''WesternAnimation/TheSimpsons''; a child photographer tries to get Maggie to smile by increasing the pitch of his voice, only to dejectedly realise that the balloon just contains air.
* Happens in the opening sequence for ''WesternAnimation/MikeLuAndOg''.
* Mr. Funny did this once in ''WesternAnimation/TheMrMenShow''.
* In one episode of ''WesternAnimation/TheRobonicStooges'', Curly inflates himself so he, Larry and Moe can escape a castle where all the exits are locked.
* In an episode of ''WesternAnimation/PhineasAndFerb''. the brothers create a soap bubble with a super-strong skin similar to a balloon. When it threatens to burst by touching the ground, Baljeet panics and starts hyperventilating - which makes the bubble grow and start rising again.
* In ''WesternAnimation/MyLittlePonyEquestriaGirls'', the human version of Pinkie Pie briefly floats around the gym at Canterlot High with a balloon she inflated.

!!Examples with bubble gum balloons:
[[foldercontrol]]

[[folder: Advertising ]]

* There was a commercial for a Skittles gum where, after refusing to share said gum with someone, a man blows a bubble with it, grabs hold, and floats away.

[[/folder]]

[[folder: Comic Books ]]

* One issue of the comic book version of ''Series/{{ALF}}'' played with this trope, [[JustifiedTrope justifying]] it with BizarreAlienBiology: Melmacians (at least when on Melmac) exhale helium.

[[/folder]]

[[folder: Newspaper Comics ]]

* In ''ComicStrip/{{Peanuts}}'', Lucy has been known to chew bubble gum and blow bubbles that make her float.

[[/folder]]

[[folder: Web Comics ]]

* ''WebComic/StupidFox'' [[http://stupidfox.net/73--bubbly does this]].

[[/folder]]

[[folder: Video Games ]]

* The Bubble Monkey in ''VideoGame/{{Earthbound}}'' has the ability to levitate himself with bubblegum.
* In ''VideoGame/SonicHeroes'', blowing gum is Vector the Crocodile's chosen method of hovering.
* The hero of ''Skuljagger'' uses a variety of gum as power-ups. The cherry gives him hovering abilities.
* In ''Sid & Al's Incredible Toons'' and ''The Incredible Toon Machine'', a pack of bubble gum is one of the objects in the game and may be used by Sid or Al to take flight.
* ''VideoGame/TheCurseOfMonkeyIsland'' has a puzzle whose solution is to inhale a helium balloon and then chew some bubble gum so that it floats out of a window. Besides this being [[RuleOfFunny physiologically impossible without Guybrush passing out from lack of oxygen]], one wonders how both helium and bubble gum were accessible in the [[AnachronismStew 17th century]].
** Guybrush is famously capable of holding his breath for a very long time.

[[folder: Western Animation ]]

* ''WesternAnimation/ChalkZone'' used the bubble gum variant of this trope in one episode where Rudy is telling a story of one of his escapades in the titular [=ChalkZone=]; while [=ChalkZone=] ''is'' a different dimension with things that make little to no sense in the real world, the trope still applies. Penny [[LampshadeHanging hangs a lampshade]] on this implausibility.
* The ''WesternAnimation/EdEddNEddy'' episode ''For Your Ed Only'' starts off with Edd showing the two other Eds some type of chewing gum he made, Ed uses this to blow a bubble and is then lifted away by it.
-->'''Edd:''' Ed, are you blowing a bubble? Heavens, I don't have data for this!
-->'''Eddy:''' HEY! Get back here with my gum!
** Later in the episode, the Eds are cornered by Sarah ready to tear them to pieces when Ed and Eddy make Edd chew the gum so they can float and escape. When he can't chew it fast enough, Ed blows into Edd's mouth causing his hat to inflate.
* The ''WesternAnimation/DuckTales'' episode "The Big Flub" centered on a bubble gum-like substance that was marketed as Pep. It allowed its user to float using the bubbles that were blown. The advertising campaign and its effect made it incredibly popular until its horrific side-effects were discovered.
* ''WesternAnimation/JohnnyTest'': Wacko once made gum with "helium crystals" that, when blown, creates bubbles capable of levitating children into the air in another one of his ultimately omnicidal plans.
* ''Series/SesameStreet'' had an animation where an aviator orders [[http://www.youtube.com/watch?v=CydzJ1rz1Y4 5 pounds of bubble gum]].
