Chemical bomb bag

Chemical bomb bag consists of a very thin plastic bag of very diluted acid (vinegar) and baking powder. When someone presses the bomb bag, the thin plastic bag in it burst. The acid and baking powder come into contact and they react chemically. Large amount of carbon dioxide will be produced and will eventually burst the bomb bag. This process shows chemical potential energy in the acid and powder converts to elastic potential energy in the bomb back. Then this EPE converts to kinetic energy of the bomb bag and sound energy.
