I have seen this experiment all over the net and knew the boys would love it! Our first attempt was a bust so we tried again and got a better result.
- Put 1/2 cup of peroxide into your bottle using a funnel
- Add food coloring
- Add a squirt of dawn dish soap
- In a separate container mix 1 teaspoon of yeast with 2 tablespoons of very warm water and let dissolve
- Pour yeast mixture in the bottle and quickly remove funnel
The result should be an Exothermic Reaction! ( Chemical change that is accompanied by a liberation of heat, as defined here)
The result is a little warm at first but it can soon be played with if the kiddos like 🙂
