Materials

Method

What happened and Why?The yeast acted as a catalyst to remove the oxygen from the hydrogen peroxide. Since this happened very fast, it created lots and lots of tiny bubbles filled with oxygen. The bottle also got warm because it created an excothermic reaction- creating heat!

Result

Elephant Toothpaste
