During an exothermic reaction, HEAT is created during the reaction.
See what happens when hydrogen peroxide is helped along its chemical reaction journey by yeast to produce some big foam fun.

The Science Behind the Reaction
This exothermic reaction results from a breakdown of the hydrogen peroxide into oxygen and hydrogen. The yeast speeds up the chemical reaction, and well, the soap is just there to capture those oxygen molecules and make a cool foam. The resulting chemical in the Erlenmeyer flask is hot as breakdown of the hydrogen peroxide is an exothermic (heat producing) chemical reaction.
