  • Don’t worry. I’ve never seen a balloon expand so much that it popped. The gases will eventually settle down and the balloon will stop expanding. You can tie it off after it has expanded. Expect some liquid to remain in the balloon from the moisture build up.

The science and explanation to this baking soda balloon experiment…

The baking soda, and vinegar are mixing together to form a gas called carbon dioxide. The gas expands. It needs room to expand and grow. If the water bottle outlet is sealed, the gas has no choice but to travel up and out into the balloon, filling the spaces up and inflating it!

Tips and Tricks for this Vinegar and Baking Soda Balloon Experiment…

  •  We tried to re-use the vinegar. It didn’t work. You have to rinse the bottle each time, and pour fresh vinegar into the bottle before starting again. 🙁
  • The reaction from the baking soda and vinegar is quick. Make sure you have the kid’s attention before you combine the two
  • Try to keep the baking soda and vinegar separate until you are ready to watch the balloon inflate. You don’t want to start a reaction in the vinegar before you are ready. Once the vinegar has reacted with the baking soda the effect will not be as strong 
  • You can reuse the balloons, but eventually the neck of the balloons will give out and rip from use
