Confession: I escaped 18 years if education without taking one single chemistry class. I’m thinking this explains my love of all things reactive when it comes to activities with my kids.
Today’s reaction? “Elephant’s Toothpaste.”
I mean c’mon?! That just sounds cool. Usually my activity list is pretty simple requiring little in the way of supplies, but I also try to plan accordingly when the random special ingredient comes up. In this situation, that special ingredient was 6% hydrogen peroxide found at a beauty supply store. (There may be a beauty supply store next to the craft store… I’m just sayin’.)
- 1 baking sheet with a rim
- 1 16 oz. soda bottle
- food coloring
- 1 package yeast diluted in 2 tbsp. warm water
- 1 squirt dish soap
- 1/2 cup 6% hydrogen peroxide solution
Our yeast was crazy old, so our reaction was less dramatic than it might be with brand new yeast… but Eleanor was still thrilled. Add the hydrogen peroxide and a few drops of food coloring to your bottle.
Squirt in your dish soap. When ready, add the yeast and watch what happens.
I was hoping for a more explosive reaction, but this was still pretty cool. Eleanor was delighted by the slow progression of the elephant’s toothpaste and was eager to try it again.
For someone who’s closest encounter with chemistry is mixing vinegar with baking soda, I was down with this reaction. I liked the fizzing and the erupting and the experimenting.
I think… Eleanor did too.
