What makes hydrogen peroxide explode in this elephant’s toothpaste experiment? Museum Educator Jeannine explains how potassium iodine acts as a catalyst to cause hydrogen peroxide to break down faster into water and oxygen gas in an exothermic reaction, producing heat, as well as a foamy explosion thanks to the addition of soap! #Chemistry #STEMEducation #ScienceExperiment #Science #WomenInSTEM | Museum of Science, Boston

The elephant toothpaste STEM activity is to demonstrate how exothermic reactions work. The washing up liquid when mixed with hydrogen peroxide and oxygen creates a foam, or 'elephant toothpaste', that's fun to watch grow. The oxygen-filled bubbles, which make up the foam, are actually the remainder of what happens when the hydrogen peroxide breaks down into water (H2O) and oxygen (O2). The bottle will feel warm to the touch because this is an exothermic reaction in which energy, in the form of h
