Can you inflate a balloon up without blowing it up with your mouth?
We think that a balloon can be blown up without using your mouth.
- Empty water bottle
- 2 Funnels
- 2 Tbls. Baking soda
- 1/2 Cup Vinegar
Make sure the balloon covers the whole opening on the bottle.
Do not shake the water bottle with the vinegar and baking soda inside.
Do not remove the balloon after you pour the baking soda into the bottle.
Watch us in action:
The Science Behind It
When you mix vinegar, an acid, with baking soda, a base it creates a chemical reaction and forms carbonic acid. When the bubbles are produced it breaks the carbonic acid down and forms a gas called carbon dioxide. The carbon dioxide inflates the balloon.
Our hypothesis was correct and you can inflate a balloon with out air.
