Relatively harmless stink bombs consist of a mixture of ammonium sulfide, vinegar and bicarbonate, which smells strongly of rotten eggs. When exposed to air, the ammonium sulfide reacts with moisture, hydrolyzes, and a mixture of hydrogen sulfide (the rotten egg smell) and ammonia is released.
Another mixture consists of hydrogen sulfide and ammonia mixed together directly.
At the other end of the spectrum, the governments of Israel and America are both developing stink bombs for use by their law enforcement agencies and militaries for riot control and as “area denial” weapons. A stink bomb that could be launched with arrows was invented by Leonardo da Vinci.
In the UK, stink bombs are prohibited under Regulation 10 of the Dangerous Substances and Preparations (Safety) Regulations 2006 which prohibit the supply of dangerous substances and preparations intended to cause amusement, such as stink bombs and sneezing powder.
