This demonstration is called Elephant’s Toothpaste because the chemical reaction produces a large foamy mess that looks like toothpaste squirting out of a tube. We want to do this project because we want to show how this science experiment works and tell the reactions of it.
How It Works:
This large demonstration uses hydrogen peroxide, sodium iodide and soap. First, we pour in the hydrogen peroxide, then the soap and finally the sodium iodide.
The yeast contains an enzyme called Catalase that breaks down hydrogen peroxide (H2O2) into oxygen, gas, and water. The oxygen gas gets trapped by the soap, and you get a large foamy solution that squirts out of the top of the bottle! hydrogen peroxide (3%) dish soap dry yeast warm water
