Today we are making elephant toothpaste.
How ever this isn’t for a pachyderm.

You’ll need:

Empty plastic bottle
Dry yeast (found in the baking section of the grocery store)
Warm water
Liquid dish soap
3% hydrogen peroxide
Measuring cups
Measuring spoons
Safety glasses
Large tub or tray to catch the foam
Location for the activity that can tolerate spills (of hydrogen peroxide as well as possibly food coloring), such as a kitchen or bathroom—or an outdoor location
Liquid food coloring (optional)
Different-shaped bottles or glasses (optional)

First take a bottle and put 1/2 cup of hydrogen peroxide into the bottle.
Add some dish soap to the bottle and mix the two well.
For fun add food coloring.
Then mix 1 tablespoon of dry yeast with three cups of warm water and mix
Take the yeast mixture and pour it into the bottle.
Then watch as the bottle foams up!

Hydrogen peroxide breaks down into oxygen and water slowly over time, but the yeast is a living organism and has a chemical acts as a catalyst and speeds up the process. The dish soap catches the oxygen and water made.
