CO2 Explosion

This is a safe explosive device that you can make from ordinary kitchen materials.

  • Bicarbonate of soda
  • Vinegar
  • Tissues
  • Zip lock bags
  • Measuring spoon and cup
  • Baby powder

You need....

Measure and spread about one full tablespoon of bicarbonate of soda on an open tissue paper

Fold the tissue paper into a small envelope with the bicarbonate of soda inside. Make a tissue envelope
Insert it into an ordinary zip lock bag.
Measure about 2 tablespoons of white vinegar and pour it into the open zip lock bag. Add the vinegar
Quickly seal the bag air tight. Give it a vigorous shake to make sure all the vinegar mixes with the bicarbonate of soda. Seal it well!
Sprinkle some baby powder on top and wait... Sprinkle
Waiting Explode!



As the vinegar and bicarbonate of soda mix a chemical reaction occurs.

Mixing an acid and a base give off CO2.

The bag inflates and eventually explodes along the zip lock seam with a loud bang sending a cloud of baby powder up into the air.


This is a perfectly safe explosive device. The only after-effects is a big mess!  Try experimenting with different sizes of zip lock bags and different mixes of bicarb and vinegar to give your kitchen “bomb” a fused timer. This gives you a chance to make a quick get away after you have planted it under somebody’s chair.
