Balloon Inflate/Pop Science Experiment

Science is fun! We love doing science experiments. This experiment is a quick and fun experiment inflating or popping balloons. How big your balloon gets as well as whether it pops depends on how much baking soda and vinegar you use. We did this experiment several times and Teddy loved it each time. We used different balloon colors and changed our ingredient amount so sometimes the balloon would pop and sometimes it would just inflate. Easy, fun science experiment.


  • Balloons

  • Vinegar ( amount depends on container used)

  • Baking Soda (amount depends on container used)

  • Plastic Bottle or laboratory flask

  1. Pour the vinegar into your container.

  2. Pour baking soda into your balloon

  3. Place balloon onto the container that holds the vinegar, being sure the baking soda falls into the container of the vinegar

  4. Your balloon will inflate or pop!

We used a laboratory flask so we filled our flask 1/4 way full of vinegar and used one teaspoon of baking soda. Again, it will depend on the container you use. Some instructions for this experiment say to use 1/3 cup baking soda and a cup of vinegar for the plastic bottle.

CAUTION: Definitely be careful with this experiment because if your balloon pops you want to be sure no one gets hurt. We used safety glasses when doing this experiment. Proceed with caution and use your best judgement.
