Hot Snow - Science Play

Hot Snow 
(A.K.A. Elephant's Toothpaste)

My Little Mister was fascinated by the "snow" that bubbled out of the bottle!
He wanted to make snowballs and snow angels!
The experiment was fun, but he was disappointed we could not get in it.

The Science behind the play:
You are actually making foam AND heat.
The foam here is special because each tiny foam bubble is filled with oxygen (O2). The yeast acted as a catalyst - or helper - to remove the oxygen from the Hydrogen Peroxide (H2O2). Since this happens very fast, it created LOTS and LOTS of bubbles. 
You might have also noticed the bottle getting warm. This experiment created a reaction called an Exothermic reaction. Simply meaning it released or created heat.

The foam created is just water, soap and oxygen so it is easily cleaned up and any remaining liquid in the bottle can be poured down the sink!


  1. What a fun experiment! I used to love this kind of thing as a kid.

  2. This is something my kids would love too!

  3. That is really cool! I am going to have to try this out with the kids. We love trying out different things that we can do with things right at home. :) Visiting from Our Everyday Harvest's blog hop. :)

  4. What a fun idea! Thanks for linking up to my Pin Me party!

  5. This is excellent! I know my kids would absolutely love doing this!! Stopping by from the made by little hands linky. I wanted to also invite you to link up in our party. Lots of creative ideas have been shared and I know yours would fit right in!

  6. very cool experiment! Pinned for our science fun at home :)

  7. WOW!!! I am going to try that just for fun by myself (I'm in my 40's hahaha)!! Thank you so much for sharing on my blog hop.

    1. J tried all kinds of things before I had Little Mister. Now, he;s just my front! LOL

  8. I have been looking for some more Science experiments to do with my girls. And they would LOVE this. Thanks so much for sharing on We Made That!
