Elephant toothpaste is a foamy substance caused by the rapid decomposition of hydrogen peroxide. This is often used for classroom demonstrations because it requires only a small amount of ingredients and makes a "volcano of foam". This is also known as the "Marshmallow Experiment" in some cases, but should not be confused with the psychological Marshmallow experiment.
