4-H Virtual Recess: Fizzy Foam Fun

Tobie Blanchard, Boe, Esther C.

Teach kids how chemical reactions are impacted by a catalyst.

A catalyst is a material that speeds up reactions but doesn’t react itself. In this case, we’ll create a colorful foam fountain by adding yeast to a mixture of chemicals.

Questions to engage kids:

  • What did you observe before adding in the water and yeast?
  • What changed when you added in the mixture?
  • What do you notice if you touch the bubbles?


  1. Combine warm water and yeast in a bowl and set aside. Put bottle in the baking pan to avoid mess.
  2. Pour hydrogen peroxide into bottle. Add in a few drops of food coloring and a couple squirts of dish soap.
  3. Pour water/yeast mixture into bottle. Remove funnel quickly and stand back.
