Stink Bomb Facts and Safety This stink bomb forms ammonium sulfide,(NH4)2S, which is the same chemical used in commercial prank or trick stink bombs. The ammonium sulfide is produced as a result of a reaction between hydrogen sulfide and ammonia: H2S + 2 NH3 → (NH4)2S The vapor is flammable and associated with hydrogen sulfide gas (rotten egg smell that is toxic in high concentrations), so only make/use the stink bomb in a well-ventilated area, away from heat and flames. Adult supervision is recommended. More Stink Bomb Recipes Disclaimer: Please be advised that the content provided by our website is for EDUCATIONAL PURPOSES ONLY.
