- 1/2 cup 6% hydrogen peroxide (sold in beauty supply stores)
- 2 tsp. yeast
- 3 tbsp. warm water
- dish detergent
- food coloring
- empty 16oz plastic bottle
- funnel
First step: Add in the hydrogen peroxide (An adult will want to do this stage). Next, add in approx. 10 drops off food coloring.
Next, add in your dish soap and swirl to combine
In a separate cup, combine your yeast and water. Stir until smooth. Using a funnel, add into the hydrogen peroxide mix.
Watch it explode! It builds slowly, but the bubbles just keep coming! The foam is warm and safe to touch. The pictures do not do this activity justice! Very fun!
And it wouldn't be my son if his favorite part wasn't the hose clean up!
