Re: Elephant toothpaste I see it now. Pour 1/2 cup of hydrogen peroxide into the bottle. After completing the activity, students read about physical and chem. introduces students to two key concepts of physical science-that liquids are a state of matter and that each state of matter has its own identifiable properties. The iodide ion catalyzes the decomposition of hydrogen peroxide, generating oxygen gas which causes the soap to foam up and shoot up out of the cylinder. Elephant's toothpaste is a foamy substance caused by the rapid decomposition of hydrogen peroxide (H2O2) using potassium iodide (KI) or yeast and warm water as a catalyst. The hydrogen peroxide fumes can be harmful if inhaled in large quantities. Potassium nitrate is also an aquatic environmental nasty, parabens can disrupt the hormones in animals and so on and so on.
