elephant toothpaste
Peroxide decomposition demo
Elephant toothpaste is a foamy substance created by rapidly decomposing hydrogen peroxide, producing a dramatic eruption that resembles toothpaste squeezed from a giant tube.
It's a popular chemistry demonstration in classrooms and science videos: The kids loved making elephant toothpaste at the science fair.
