How To Blow Up a Balloon with Baking Soda and Vinegar

For the baking soda and vinegar balloon experiment, fill your empty water bottle about 1/3 of the way full with vinegar.

Use the funnel to fill the balloon with baking soda. It doesn’t need to be all the way full–we didn’t measure, but I’d say it was about 2-3 tablespoons of baking soda.

This fun balloon experiment teaches kids how to blow up a balloon with baking soda and vinegar. Kids will love to do this balloon science experiment! This would make an easy balloon science fair project. This science experiment for kids is will teach them how to blow up a balloon without your mouth.

While you have the baking soda and vinegar out, you should make a volcano, too!

How does this work?

The baking soda and vinegar create an acid/base reaction. The baking soda is the base and the vinegar is the acid. When the two are mixed they work together to create a gas called carbon dioxide (CO2). Gasses need a lot of room to spread out and the carbon dioxide starts to fill the bottle and then moves into the balloon to inflate it. Pretty cool, huh?
