"You swim in that, you'll be the soup in no time flat! Boneless, too!"
The pool filled with Hollywood Acid
is the go-to Death Trap
for any Mad Scientist
that doesn't have access to a Lava Pit
- usually bubbling a sickly green color
, it will melt the flesh off your bones and leave nothing but a bleached skeleton, if that. Can be used both for moats near precarious bridges and lowering heroes into. Acid pools are generally treated as green variants of the Lava Pit
and used in a similar manner as obstacles or execution methods.
Highly impractical in Real Life
due to the nature of acid, particularly if bubbling. Acid is often produced when highly caustic negative ions are dissolved in water, and they are quite capable of escaping, particularly if in high enough concentrations as to remove flesh from the bone. These remain caustic and are quite likely to damage anyone nearby (almost like a chemical variant of Convection Schmonvection
Strong acid is also extremely poisonous to breathe, so the air would be fatal long before its first victim could fall into it, unless it was from a substantial height; and even then it would have a substantial stench even from a great distance, which would drive anyone away if they had a choice.
The counterpart on the opposite end of the pH scale is the pool of lye, which shows up typically in industrial vat form.

The man killed himself the next day.

- Subverted in an episode of Kung Fu, where young Kwai-Chang is ordered by Master Po to cross a plank over an acid-pit full of human skeletons, and blind Master Po demonstrates by walking across it himself. Kwai-Chang obeys and walks across the plank, but falls into the pit halfway across — only to find that it's only full of warm water, and the skeletons were made of paper; the "test" was simply a lesson to teach him that "fear is like a magnet" that pulls a man in its direction.
