Have you ever wondered what elephants brush their teeth with? Well this science experiment will help you find out!
Science Stop: Each tiny bubble made in this foamy experiment is filled with oxygen. The yeast acts as a catalyst, or helper, to remove the oxygen from the hydrogen peroxide. Since it does this very fast, it creates a bunch of bubbles.
What You’ll Need:
- Clean water bottle (or glass milk bottles)
- 1/2 cup 6% solution hydrogen peroxide liquid
- 1 tablespoon (one packet) of dry yeast
- 3 tablespoons of warm water
- 1 tablespoon of liquid dish soap
- Food coloring
- Place bottles in a tray or on a washable surface.
- Pour 1/2 cup of hydrogen peroxide into the bottle.
- Add about 10 drops of food coloring into the bottle.
- Mix in 1 tablespoon of liquid dish soap into the bottle and swish the bottle around to mix it (this will create more foam in the reaction).
- In a separate small cup, combine the warm water and yeast together and mix for about 30 seconds.
- Pour the yeast water mixture into the bottle (a funnel helps).
