Elephant Toothpaste PDF


Product Description

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; excellent introduction to colloids, exothermic reactions, or catalysts. Grades 2-8
