How To Fill Balloons Quickly Without Helium
We seem to be on a science kick this week! Believe me, your kids will want to do this more than once. Here is a simple chemistry experiment that you can do with everyone’s favorite baking soda and vinegar reaction! Making a volcano is fun, but did you know that you can also use baking soda and vinegar to blow up a balloon? We used this experiment to learn about gases.
What To Do:
1. Using your funnel pour vinegar into your bottle. You only need to fill about 1/3 of the bottle.
2. Using another (dry) funnel pour baking soda into your balloon. Fill the balloon approx. 1/2 way.
3. Cover the top of the bottle with you balloon. Make sure you don’t let the baking soda spill into the bottle prematurely.
4. When ready, lift your balloon and let the baking soda fall into the vinegar.
5. Watch as the mixture fizzes, bubbles & expands your balloon!
6. Discuss how the baking soda & vinegar produce a gas which fills the balloon.
The science behind it – Baking soda and the vinegar create an ACID-BASE reaction. When combined/mixed they create a gas – carbon dioxide. Gasses need room to spread, so the carbon dioxide fills the bottle and then moves into the balloon inflating it.
