Elephant Toothpaste

This is such a fun little science experiment that is a variation on the volcano explosion we all know from elementary school science class. My kids were amazed at how thick the mixture came out! We will definitely be doing this a lot!

I got the idea and the recipe here:

*2 tablespoons warm water
*1 teaspoon yeast
*1/2 cup 6% (or higher) Hydrogen Peroxide. (I couldn't find this in stores so I ordered it from Amazon.)
*4-5 drops of food coloring
*squirt of dish soap.

1. Set a bottle or a jar in the middle of a cookie sheet.
2. In a seperate bowl mix water and yeast together and let sit until dissolved.
3. Mix the hydrogen peroxide, the food coloring and the dish soap in your bottle.
4. Pour the yeast mixture into your bottle.
5. Watch the reaction!
