Elephant's Toothpaste Explosion - Experiment At Home - Scitech Hydrogen peroxide (H2O2) decomposes naturally into water (H2O) and oxygen (O2). By adding a few more ingredients we can make a huge, bubbly reaction to visualise this process. In this experiment we add dish soap, to help create bubbles, and a catalyst — which is a special chemical that allows us to fast forward a reaction.

Elephant Toothpaste , a hydrogen peroxide chemistry experiment In many situations, hydrogen peroxide is quite stable, but, there are ways to make it break down. In this experiment, 30% or 35% hydrogen peroxide is mixed with some liquid soap, and then a catalyst is added, to make the peroxide rapidly break down. The catalyst is generally a metal, and once it is added, the peroxide breaks down very rapidly.
