Demonstration Only Adult Run Experiment:
Take an empty 2 Liter Soda bottle and using caution add 1 cup of 40 Volume (12%) Hydrogen Peroxide
using a funnel. Add a few squirts of Dawn Dish Soap. Swirl gently. Take one full packet of Dry Active Yeast and add it to 4 Tablespoons of very warm water. Stir well. Place 2 Liter bottle with Hydrogen Peroxide and Soap in a container and using a funnel add yeast mixture. Immediately remove funnel and step back and watch the show! The foam and bottle will be VERY warm - so please have an adult cautiously check the temperature before allowing children to play in the foam. As with the above experiment, the soap foam is soap foam - no peroxide is left - so it is safe to handle once it has cooled.

It's HILARIOUS. You can check out her Elephant Toothbrush here!

To make your own Elephant's Toothpaste you will need:
Close adult supervision
Safety goggles for your child if they are going to be involved in any mixing/pouring
Warm Water
Funnel
Narrow-necked bottle (sized around 15 ounces)
Colorations Liquid Watercolors
(What are Liquid Watercolors?) or Food Coloring (optional)
(What are Liquid Watercolors?) or Food Coloring (optional)Glitter (optional)
*6% (20 volume) Hydrogen Peroxide is a bit of a specialty item - you will need to find a nearby Beauty Salon Supply shop (or click the link to purchase it on Amazon). The reaction will still work with 3% Hydrogen Peroxide (the kind you can buy at a drugstore or grocery), but it is much less dramatic.

Mix well.
Into your narrow-necked bottle, add 1/2 cup of 6% (20 volume) Hydrogen Peroxide(I recommend an adult does this step for safety), any coloring you would like (Colorations Liquid Watercolors or Food Coloring), glitter (if you'd like), and a few squirts of Dawn Dish Soap. Swirl it all carefully (this is another job I'd recommend an adult do for safety).

Swirl it all carefully (this is another job I'd recommend an adult do for safety).Place your bottle in a container to catch the mountain of foam (we used a glass baking dish), then add the yeast mixture through a funnel. Quickly remove the funnel and enjoy the show!
