The kids loved this since experiment. The chemical reaction creates foam that shoots up out of the bottle after about a minute or so. The kids had fun playing with the warm foam for a while.
Want to make it with your kids!? Here are the materials and instructions.
Materials:
A plastic bottle (works better with a narrow neck)
1 cup of hydrogen peroxide
1/2 cup of Dawn dish detergent
3-4 drops of food coloring (I used blue, you can use any color)
1 teaspoon yeast dissolved in 2 tablespoons of very warm water
Funnel
Something to contain the “toothpaste” (We used a bake glass pan)
Instructions:
Using separate mixing cups mix the hydrogen peroxide and food coloring in one, and In the other mix the yeast with water.
Can you tell that they love each other!?
Pour hydrogen peroxide into the bottle
Measure the cup of dawn and add it to the plastic bottle
Yeast with water
It’s going up
Watching it explode!
My kid wanted to pay with the foam forever.
