Stick with the safer 3% hydrogen peroxide you can buy at the drugstore. All you need is some hydrogen peroxide, dish soap, dry yeast, and warm water. Part 2: Questions about 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. However, the overall temperature of the mixture will actually decrease as the reaction takes place. Food coloring can color the film of the bubbles so you get colored foam. Grades 6-8 - focuses on chemical reactions WebElephant Toothpaste Release the awesome power of oxygen with an oozing, foaming and safe chemical reaction.
