Can you blow up a balloon without using your mouth? In this simple but cool science experiment, we’re going to show you how to blow a balloon without using your mouth. Do it with only a few everyday items that you probably will find in your kitchen. It is a great experiment for young children because the set-up is simple and this experiment can be demonstrated by teachers at school.

Like other science experiments on science tidings (science blog and website), we have enclosed a printable and shareable instruction card at the end of this experiment. For the completion of this really cool science experiment (how to blow a balloon without using your mouth), we have also explained why this occurs later on in this post.

Materials required:

  • Small and empty water/soda Bottle
  • Balloon
  • Baking Soda
  • Vinegar
  • Funnels
  • Teaspoon

Tip: It is best to have two funnels, one for filling the bottle with vinegar and one for the balloon. If you only have one funnel, it is important that you completely wash and dry the funnel after you add the vinegar and before you put it into the balloon.

Step by step instructions on how to blow a balloon without using your mouth:

How to blow a balloon without using your mouth science experiment:-

Vinegar into Bottle

Watch in surprise how the balloon gets filled up.


The science behind this balloon blow-up experiment:

Baking soda + Vinegar (acid) ———> Carbon dioxide (gas)

This carbon dioxide occupies the balloon and inflates it.

The baking soda and vinegar chemical reaction will continue to inflate the balloon as long as there is still baking soda and vinegar to react. Once the reaction between baking soda and vinegar has stopped, the balloon will slowly begin to deflate.
