How to do, elephant toothpaste with kids, stem science, camp experiment 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-


but watch out. Could get very hot. So make sure that you wait a couple of minutes before you let your little ones in there and wear gloves and goggles.


And, of course, my older kids wanted to just play with the soap solution and make a mess and throw it all over our yard. So happy Sciencing!
