Stink Bombs
Description: When crushed or broken, these stink bombs let off an overwhelming smell of rotten eggs! There are 3 small glass vials (bombs) per pack -- each with enough potency to cause some serious damage.

A stink bomb or stinkbomb is a device designed to create an unpleasant smell. They range in effectiveness from simple pranks to military grade chemical agents.
At one end of the spectrum, relatively harmless stink bombs consist of aluminum sulfide, which smells strongly of rotten eggs. When exposed to air, the aluminum sulfide reacts with moisture, hydrolyzes, and hydrogen sulfide is released. Other popular substances on which to base stink bombs are thiols with lower molecular weight, e.g., methyl mercaptan and ethyl mercaptan — the chemicals that give odor to skunks and are added to natural gas. A variation on this idea is the scent bomb, or perfume bomb, filled with an overpowering "cheap perfume" smell. Prank stink bombs and perfume bombs are usually sold as a 1- or 2- ml sealed glass ampoule, which can be broken by throwing against a hard surface or by crushing under one's shoe sole, thus releasing the odorous liquid contained therein.
