Overall Reaction: 2 H2O2 (aq) → 2 H2O (l) + O2 (g) NCSU – Dept. What is the chemical equation for Elephant Toothpaste? More recently, it’s been used at the 2019 Miss Virginia pageant and for gender reveals. It is commonly used in classrooms to demonstrate an exothermic reaction. ![]() What is the purpose of the Elephant Toothpaste experiment?Įlephant’s toothpaste is a foamy substance that’s created when you combine water, hydrogen peroxide, yeast, and dish soap. With just a few simple ingredients, you can make something that looks like toothpaste being squeezed from a tube-but so big, it must be for elephants! This activity is not recommended for use as a science fair project. The resulting foam (“elephant’s toothpaste”) demonstrates a chemical reaction that can “explode” in student engagement! Can Elephant Toothpaste be a science project? Is Elephant Toothpaste a chemical or physical reaction?Ĭentral Focus: In this activity, students will observe a chemical change by combining a yeast mixture with hydrogen peroxide and dish soap. The experiment created a reaction called an exothermic reaction, which means it not only created foam, it created heat! The foam produced is just water, soap, and oxygen, so you can clean it up with a sponge and pour any extra liquid left in the bottle down the drain. ![]() 24 What is an example of a catalyst in everyday life? What type of experiment is Elephant Toothpaste? ![]()
