Hard Science's video: Exploding Elephant Toothpaste - Hard Science

WATCH OUTTAKES HERE: http://testu.be/1cYQhkx Anthony and Tara teach you how to make a very exciting exothermic reaction with hydrogen peroxide. It will also keep your pet elephant's teeth clean. Experiment Tips: -Experiment's reaction produces heat, be careful not to touch until it has a chance to cool. -30% hydrogen peroxide can bleach/burn so be sure to avoid contact with skin and clothing. -Swirling the chemicals together after combining gave a faster and stronger reaction. Relight a Match http://chemistry.about.com/od/chemistrydemonstrations/a/elephanttooth.htm A small flint or ember from a dying match placed above the bubbles will re-ignite the match due to the oxygen being released. All Living things Contain Peroxides http://looseinthelabscience.com/downloads/ElephantToothpaste2011.pdf Hydrogen peroxide is naturally produced in organisms as a by-product of oxidative metabolism. Nearly all living things possess enzymes known as peroxidases, which harmlessly and catalytically decompose low concentrations of hydrogen peroxide to water and oxygen. Exothermic Reaction http://reekoscience.com/Experiments/ElephantToothpaste.aspx #.Up46W2SglgI The bottle will feel warm to the touch due to the exothermic reaction. Exo meaning exiting or leaving and thermic having to do with measuring temperature or heat. . So, an exothermic reaction is a chemical reaction where the heat stored in the chemical bonds is released and goes into the environment.
