Elephant toothpaste is a very easy and funny science experiment, which results in a rapid eruption of huge amount of foam.
Things we need:
-10% hydrogen peroxide
-food coloring
-dish soap
-yeast
Elephant toothpaste is the decomposition process of hydrogen peroxide, while yeast / potassium iodide works as a catalyst to break down the hydrogen peroxide into oxygen and water. Soap will then mixed with the oxygen and water, which turn into foam.
