Use candy to make these balloon inflate!

We all know popping candy is fun to eat, but did you know that you can inflate balloons with it? Let’s take a look at one of the cool ways that the STEM field can be brought into your house, using a few ingredients that are easy enough for the littlest of scientists to do.

In this experiment, balloons inflate because of a gas called carbon dioxide, or CO2 for short. The chemical reaction happens when the popping candy starts to dissolve in the soda — all of a sudden there’s a bunch of extra CO2 from the candy-soda mix and the balloons start to inflate. Pretty neat, huh? The next time you want to show someone a really cool way that you can be an at-home scientist, just grab these ingredients and follow our instructions to make a candy-powered inflating balloon!

Magic Balloon


  • Small kitchen funnel
  • Balloons
  • Popping candy
  • Pop bottle


  • Place the narrow end of the funnel into the mouth of the balloon, and slowly empty the packet of popping candy into the balloon. Make sure the funnel is empty by gently tapping the top.
  • Stretch the opening of the balloon over the mouth of the bottle of soda. The balloon should hang down beside the bottle.
  • Grab the balloon at its lowest point, lift it up, and release the popping candy into the soda. Then watch the balloon magically inflate!
