Dip

The Dip] (aka Toon Acid') is a green, ghastly chemical invention seen in Who Framed Roger Rabbit. It was created by Judge Doom and is feared by all toons, as it is Doom's preferred method of passing punishment.

According to Lieutenant Santino, it's a mixture of turpentine, acetone, all of which are paint-thinners, and benzene, a natural constituent of crude oil, and one of the most basic humans petrochemicals. While it is harmless to humans (Eddie was seen running through an ankle-deep pool of it), any toon that comes in contact with it will melt slowly and painfully, and is apparently the only surefire way to kill a toon (although Eddie Valiant gets most of The Toon Patrol members to laugh themselves to death).

Ironically, Judge Doom ends up being dipped himself near the end of the film, after revealing himself to be actually a toon. He invented a vehicle machine, called "The Dipmobile", which was then destroyed by an oncoming train.

Only three characters die from the Dip: the Toon Shoe, Smarty and Judge Doom. Benny the Cab comes into contact with it, but survives.
