Product Description
Elephant Toothpaste by Bryce Hixson
Streamers of foam erupt from a 2-liter pop bottle and hit the rafters when potassium iodide is mixed with concentrated hydrogen peroxide. Water, oxygen, and a substantial amount of heat are released almost instantly and trapped in liquid detergent to create a hot, steamy pile of foam. Very entertaining, easy to do, and an excellent introduction to colloids, exothermic reactions, and catalysts.
