Hydrogen Peroxide Volcano | Arizona Science Center The hydrogen peroxide volcano, also called "Elephant Toothpaste" demonstrates how a catalyst works in chemistry. Hydrogen peroxide naturally wants to break down into water and oxygen (2H 2 O 2--› 2H 2 O + O 2). This process usually happens too slowly to be easily perceived and this is where our catalyst comes in.
