Elephant Toothpaste: Science Experiment for Kids

I found this idea at Preschool Powol Packets.

1.  Set a soda pop bottle in the middle of a pan to catch the toothpaste.

2. Mix 2 Tablespoons warm water and 1 teaspoon yeast  in a separate container and swirl together for a minute.  The yeast will catalyze (or speed up) the reaction.  

3.  Mix these in your soda pop bottle:

• 1/2 cup 6% hydrogen peroxide.  It is important to use at least 6%.  You can use 8% or more (available on Amazon), or you can Salon Care Professional Stabilized Formula. 
• 4-5 drops food coloring
• squirt of dish soap

4.  Pour the yeast mixture into the soda pop bottle...and be amazed!
