Elephant toothpaste is a fun experiment that you can make with household ingredients! The kids will love seeing the fun explosion, and they can play in the foam afterwards!


I’ve been talking about cousin camp all week because we did so many fun experiments! We made glow in the dark slime, lava lamps, ice eggs, elephant toothpaste and we had an awesome ninja warrior course! It was a fun-packed weekend!

Elephant toothpaste was very easy to do, like everything else we did, and of course the kids loved it! I had two water bottles ready for each kid, and we put them inside plastic totes so we didn’t have a huge mess all over the table.

We mixed the yeast and warm water in one bottle, and had the dish soap and food coloring mixture in the other one. When we got everyone’s bottles ready, everyone got to do their experiments at the same time. It was pretty fun to see their expressions! 

After they were done exploding, the kids played in the foam for a while and few kids melted their ice eggs in the foam.
