Elephant Toothpaste , a hydrogen peroxide chemistry experiment
Elephant toothpaste #3 – classic (Catalyst: not stated) This one is more a “classic“. The bottles have a small mouth, so the toothpaste looks like toothpaste. (In video #1 the stream of bubbles was fatter, and in video #2 there’s no soap.) In this version, there are two small-mouthed bottles, each making elephant toothpaste, side by side.
