Magically blow up a balloon

Experiments | 6-12 yrs | Video

Have to blow up balloons for a party, but don’t feel like wasting your breath? Read on for a shortcut. Bonus- it can serve as a party trick too!


  • Balloon
  • Vinegar
  • Baking Soda
  • Bottle/Funnel


  1. Pour the baking soda in the funnel.
  2. Next, add the vinegar.
  3. Cover the mouth of the funnel with the balloon.
  4. Watch the balloon inflate!


The baking soda and the vinegar create an ACID-BASE reaction and the two chemicals work together to create a gas, carbon dioxide.

Gases need space to move and therefore the gas moves into the balloon and inflates it.


Do this experiment with Baking Soda, Vinegar and Balloon. You will find out what happens. Can you write the chemical equation for this process? What are the uses of baking soda and vinegar? How are they used in cooking? How is carbon dioxide useful and to whom?
