How to do elephant toothpaste, stem kids science experiment- Home school and camp ideas

We had so much fun with this experiment for our homeschool science project; Elephant Toothpaste!




we got a 16 ounce plastic

soda bottle, or the bubbly water,


half cup hydrogen peroxide.

We got ours, 3% solution, which should be a little bit less of a reaction but that's all we could find at the time- or you can get a 6 percent solution at a local drugstore


get a tablespoon of dry yeast for each bottle

three tablespoons of warm water

in a separate container: liquid dish, soap, and food coloring


📣Make sure you have an adult pour  the hydrogen  peroxide into the bottles


- add drops of your  favorite food coloring at a tablespoon of liquid dish, soap and mix it well to the peroxide in the clear bottles


in a separate small cup combine: The warm water and the yeast  together for about 30 seconds


and then you're going to pour all that into the funnel to watch the foaminess  began-
