History Main / AcidPool

* ''TabletopGame/DungeonsAndDragons'' adventures have had a lot of these over the years. For example, [=WG5=] ''Mordenkainen's Fantastic Adventure'' had an Acid Pool so concentrated that anyone jumping in would be instantly killed.
** Also, D&D third edition averts the "harmless fumes" - if you approach a large vat of acid, you can suffer constitution damage from inhaling the toxic mist.
* Tyranids of ''TabletopGame/Warhammer40000'' use "digestion pools" to absorb the biomass of planets, and their no longer needed forces.

* Several of the areas in ''Franchise/{{Metroid}}'' (for example, Brinstar in the original game) have acid pools which only damage Samus should she fall in. Perhaps justified because of her PoweredArmor.

* In the Film/JamesBond film ''Film/NoTimeToDie'', BigBad Safin has a "farm" of the deadly bio-technological virus Heracles in his base. The liquid in said farm is acidic enough for the workers to wear {{hazmat suit}}s, and the body of a bodyguard as well as the film's resident [[MoreDespicableMinion despicable]] MadScientist get a deadly bath in it.

* ''[[VideoGame/MegaMan11 Mega Man 11: Gears of Fate!!]]'' has this as GrimyWater within the Chemical Plant stage that Acid Man and his minions haunt. Certain enemies can use their acid to make the water more corrosive. If the water becomes green, it will become so corrosive that Mega Man will take damage trying to swim in it.

* ''Videogame/{{Deltarune}}:'' The Queen's castle in Chapter 2 has some massive ones, that you thankfully cannot fall into but still need a special pedalo and bridges to cross. Part of why the Queen's doing this is because she herself drinks acid like it's wine and greatly enjoys it, so it has measures of ConspicuousConsumption.

* In ''VideoGame/SpiderManVsTheKingpin'', Mary Jane is kidnapped mid-game and hung over one of these and the player has to defeat the Kingpin before she's killed. Leading to two ([[TheHeroDies three]] is the Sega CD version) endings depending if you saved her.

** The [[Sixth Doctor]] story "Vengeance of Varos" gained instant notoriety for a scene in which the Doctor is fighting a pair of mooks and (accidentally, though it's hard to see the way it was filmed and cut) tips one of them into a bubbling acid pool, only to watch in horror as the mook he knocked in ''grabs the other mook and pulls him in too''.

* The [[Series/DoctorWho Sixth Doctor]] story "Vengeance of Varos" gained instant notoriety for a scene in which the Doctor is fighting a pair of mooks and (accidentally, though it's hard to see the way it was filmed and cut) tips one of them into a bubbling acid pool, only to watch in horror as the mook he knocked in ''grabs the other mook and pulls him in too''.

* The futuristic version of Lexcorp Tower following the Y2K storyline in ''Franchise/{{Superman}}'' comics has one, as described in ''Comicbook/ActionComics'' #765. The chairs in the conference room all have {{Trap Door}}s leading to it.

[[folder:Fan Fic]]
* In ''FanFic/AndIfThatDontWork'', Matarael (the acid dripping, a-joke-in-canon Angel) actually got to the pilot's entry plug and turned it into an acid bath.
* ''Fanfic/TheKeysStandAlone: The Soft World'' has one of these in Gothmarik Citadel, at the center of which is a treasure chest on a pedestal. Paul, [[NighInvulnerable immune to the acid]], easily fetches it, but everyone else wonders why the golem-making guy who's inhabiting the place didn't send one of his [[{{Golem}} golems]] to safely retrieve it. Oh, and it stinks, too, making everyone else cough and retreat from it.
* ''FanFic/SonicManiaTheNovelization'': In the Chemical Plant, Eggman captures Tails and Knuckles and suspends them over a tank of acidic Mega Mack, forcing Sonic to beat him in a game of [[VideoGame/DoctorRobotniksMeanBeanMachine Mean Bean Machine]] to save them.

* Tyranids of ''TabletopGame/{{Warhammer 40000}}'' use "digestion pools" to absorb the biomass of planets, and their no longer needed forces.

** The [[WombLevel Master Fortress]] form of Master Core in Smash Bros. for the Wii U is filled with these, and they're actually one of only two things in there that can cost you a life; the other being the acid-oozing walls. Touching either at 100% or higher results in an instant KO, though getting hit even at low percentages can be deadly due to the potential for you to get bounced between the pools and walls repeatedly like a ping-pong ball.
* These appear in ''[[{{VideoGame/TriOfFriendshipAndMadness}} TRI: Of Friendship and Madness]]'', and they're instant death if you fall into them. Particularly jarring as nothing else in the chapters could kill you before.
* ''[[{{VideoGame/Scribblenauts}} Scribblenauts Unmasked]]'', Maxwell is threatend with one of these by Doppleganger and Scarecrow in the Arkham Asylum level.

* ''WesternAnimation/BatmanTheAnimatedSeries''

* ''Webcomic/TheOrderOfTheStick'' had [[http://www.giantitp.com/comics/oots0541.html that little incident with O-chul]] getting dunked into an acid pool with spikes at the bottom and [[SharkPool an acid-breathing shark swimming in it]]. Interestingly, the D&D 3.5 supplement [=DungeonScape=] actually includes rules for an acid-breathing shark.

* In the final episode of ''WesternAnimation/GIJoeRenegades'', titled ''Revelations, Part 2'', Duke knocks [[BigBad Cobra]] [[VillainWithGoodPublicity Commander]] into a pool of acid and escapes with his team before [[CollapsingLair the entire mansion]] [[LoadBearingBoss explodes]]. [[spoiler: TheStinger reveals that Cobra Commander had survived, however, and he vows revenge on the Joes.]]

* ''WesternAnimation/RickAndMorty'': "The Vat of Acid Episode" obviously features one of these. However, the eponymous vat of acid is actually fake. It's a vat of a harmless green liquid implied to be Mountain Dew, with a breathing apparatus to make sure whoever falls in can stay in there until any witnesses are convinced of their death, and a supply of bones to help sell the illusion, as well as a laser for destroying any ladles that enter the vat to test it's acidity. [[spoiler:A member of the SWAT Team is convinced he's acid-proof near the end of the episode after being splashed by the fake acid. In TheStinger, he goes on ''Series/TheTonightShowStarringJohnnyCarson'' (which was still on the air in that dimension) with a real vat of acid, lowering himself into it with [[TooDumbToLive predictable results.]]]]

* In ''VideoGame/SpiderManVsTheKingpin'', Mary Jane is kidnapped mid-game and hung over one of these and the player has to defeat the Kingpin before she's killed. Leading to two ([[TheHeroDies three]] is the Sega CD version) ending depending if you saved her.

May overlap in video games with GrimyWater. See also SharkPool.

* In ''Film/HorrorsOfTheBlackMuseum'', Bancroft keeps a vat of HollyWoodAcid in his laboratory for disposing of the bodies of pesky snoopers who come too close to uncovering his secrets.

** Earlier, in ''Batman'' #451 Joker II, a sadistic but rational psychopath, decids to attempt to drive himself insane by diving into the Ace Chemical vats where the original Joker went through. To Batman's horror and a quick chuckle from Joker, whatever's in there has been switched to a ''significantly'' more corrosive formula.

* In the Creator/VincentPrice movie ''Film/HouseOnHauntedHill1959'', the house had an acid pit in the basement. (But it was OK because there was a lid on it.)
* That weird black goo at the end of ''Film/LaraCroftTombRaiderTheCradleOfLife''.

** Energized protodermis could be considered this as well; coming into contact with it means either you mutate in a random (and not necessarily helpful) fashion or you swiftly disintegrate in a painful manner.

To Batman's horror and a quick chuckle from Joker, whatever's in there has been switched to a ''significantly'' more corrosive formula since.
