But elephants don't need toothpaste, do they?
Mr. Kent, a Long Island chemistry teacher, is at it again with his after hours experiments. We like to refer to him as Mr. Wizard 2.0.
Elephant's toothpaste is what science geeks call this foamy reaction. Chemically it is the decomposition of hydrogen peroxide catalyzed by potassium iodide. To whip up some in your own sink you need Dawn soap, hydrogen peroxide and potassium iodide.
The effect is pretty and looks a lot like marshmallows, but don't touch (read: eat). It is toxic.
