What elephants brush their teeth with

"Elephant Toothpaste" can be made through the combination of hydrogen peroxide, potassium iodide, and dish soap.

First, concentrated hydrogen peroxide is mixed with liquid dish soap. Then potassium iodide - a catalyst (which speeds up the reaction), is added to make the hydrogen peroxide decompose (break down into oxygen and water). A large volume of oxygen is created and when trapped by the soap, creates a lot of bubbles!
