Step 2: Activate the Reaction

  • In a separate container, dissolve one tablespoon of dry yeast in warm water. Stir it gently until the yeast is fully dissolved.
  • Slowly pour the yeast mixture into the container with the hydrogen peroxide and dish soap solution.
  • Stand back and watch the magic unfold as the reaction begins!

Step 3: Observe and Learn

  • As the yeast mixes with the hydrogen peroxide, it acts as a catalyst, breaking down the hydrogen peroxide into water and oxygen gas.
  • The oxygen gas rapidly expands, creating an eruption of foam that resembles toothpaste squeezed out of a tube.
  • Take this opportunity to discuss the science behind the reaction with your fellow experimenters. Explore concepts such as catalysts, exothermic reactions, and the decomposition of hydrogen peroxide.
