Make your own homemade stink bombs using this easy stink bomb recipe. The stink bombs are as stinky as those you'd get at the store and can be made with common household ingredients.

Homemade Stink Bomb Ingredients

You only need three materials for this project. The "stink" comes from the reaction between the chemicals in the matches and the ammonia. While any container that can be sealed will work, a plastic bottle is recommended because it won't break.

However, another easy option is to use a plastic zip-top baggie.

  • Book of matches (20 matches)
  • Household ammonia
  • Empty 20-ounce plastic bottle with cap

Make the Stink Bomb

  1. Use scissors or a knife to carefully cut the heads off of a book of matches. Don't cut yourself.
  2. Place the match heads inside the empty 20-oz bottle. Add about 2 tablespoons of household ammonia.
  3. Seal the bottle and swirl the contents around.
  4. Wait 3-4 days before uncapping the bottle. After this time your stink bomb will be ready to be opened.
  5. Uncap the bottle when you're ready to release the stink.

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.
