p.2 Hypothesis: What type of yeast brands are more effective for making elephant toothpaste?

p.3 Abstract: Elephant toothpaste is bubbly foam what is caused by hydrogen peroxide and yeast. What types of yeast brands will be more effective? To make elephant toothpaste you take warm water and mix it with yeast. Then you pour hydrogen peroxide into a bottle with some soap. You pour the yeast and water solution in and watch the magic happen. The measurements for the materials are a 1/2 cup of hydrogen peroxide, one packet of dry yeast, 3 table spoons on water, and 1 tablespoon of liquid dish soap. The different yeast brands you can try are Red Star, Fleischmann's, Bragg Nutritional, and Saf-Instant. Saf-Instant is more effective since it took only 1 second for it to rise and it rose faster than the other brands. Fleischmann's was also good but it started out slowly then bursted while Saf-instant bloomed instantly. The other brands were too slow to create the foam and the foam didn't burst out of the bottle it just sinked like a waterfall. Adding another packet of yeast got rid of the bursting effect on all of the brands. Adding 1 cup of hydrogen peroxide increased the bursting effect on all of the brands with one packet of yeast. With the 2 packets of yeast and 1 cup of hydrogen peroxide, the effects were the same as a 1/2 cup and one packet of yeast.

p.4 How it works: The foam made is special because each tiny foam bubble is filled with oxygen. The yeast acted as a helper to remove the oxygen from the hydrogen peroxide. Since it did this very fast it created lots of bubbles and foams up and out of the bottle. This experiment creates a reaction called an Exothermic Reaction that means it did not only create foam it created heat. The foam produced is just water, soap, and oxygen so you can clean it up with a sponge and pour any extra liquid left in the bottle down the drain. This experiment is very cool and easy to do at home with little materials.
