While planning our summer fun, the kids and I have decided that Wednesday will be our Science Experiment Day. A new one every week this entire summer!
Today’s Experiment: The Soda and Pop Rocks Project
You will need:
1 pack of Pop Rocks
1 liter bottle of Soda
Funnel
1 Balloon
The first thing that you do is carefully stretch the mouth of the balloon over the small end of the funnel. Then you pour the entire packet of Pop Rocks into a balloon.
Stretch the mouth of the balloon over the opening of a bottle of soda. Carefully keep the pop rocks from spilling into the soda.
When it’s secure, dump the balloon over and empty the pop rocks into the soda
The End Result!
The secret behind the the popping of the pop rocks candy is pressurized carbon dioxide gas. Each of the tiny little candy pebbles contain a small amount of gas. These tiny carbon dioxide bubbles make the popping sound you hear when they burst free from their candy shells. Mixing Pop Rocks with soda is a physical reaction, not a chemical reaction. Dropping the pop rocks into the soda causes some of the carbon dioxide to escape from the soda. Hence the balloon inflating.
Kids.Net.Au and Encyclopedia Kids are two good sites that explained a bit more about Carbon Dioxide .
Anyone want to try this at home this summer?

Pretty cool, I’ll have to try this with the kids sometime!
So fun! I’ve never heard of this with Pop Rocks, we’ll have to try it! 😉
What??? That is awesome! We have to try that! Thanks for sharing. 🙂
My kids (even the teenagers) love it! It’s an easy and cheap experiment.
Thank you for the comments!
