How to Make an Ammonium Sulfide Stink Bomb
WHAT YOU NEED: single-edge razor blade, box of wooden safety matches, clean and empty glass jar with lid, 1 cup ammonia.
WHAT TO DO:
1. With adult supervision, use the razor blade to carefully cut off the heads of all the matches. Place the match heads in the jar.
2. Add the ammonia to the jar and immediately screw on the lid tightly. Let it sit for one week.
3. The solution can be thrown or poured directly into an area you think already stinks. Or place the jar uncapped behind a door that opens into the target room.
4. When someone enters, the door will knock over the jar, spilling the liquid.
WHAT HAPPENS: The solution stinks like rotten eggs.
WHY IT WORKS: The sulfur in the match heads combines with the ammonia to form ammonium sulfide.
