Elephant's toothpaste
Elephant's toothpaste is a foamy substance caused by the rapid decomposition of hydrogen peroxide (H2O2) using potassium iodide (KI) or yeast and warm water as a catalyst.[1] How rapidly the reaction proceeds will depend on the concentration of hydrogen peroxide.[2][3][4]
Because it requires only a small number of ingredients and makes a "volcano of foam", it is a popular experiment for children to perform in school or at parties.

Variations
YouTube science entertainer Mark Rober has created a variation of the experiment, named "Devil's Toothpaste", which has a far more pronounced reaction than the version usually performed in classroom settings.[5][6] The ingredients to create the devils toothpaste reaction are the same as the regular elephants toothpaste reaction, the only difference being that 50% H2O2 instead of the usual 35%.[citation needed]
