How to inflate a balloon without blowing

Thanks to the Science4you Chemistry kit, we have learnt how to inflate a balloon without blowing it. This is one of the experiments listed in the booklet. Click here to check out our review. I have altered a few bits of materials you need.

To inflate the balloon, you will need:

• Balloon
• Baking Soda
• Vinegar
• Rubber band
• Funnel
• Plastic bottle (small)

Method:

1. Fill the bottle halfway with vinegar.
2. Put 10g of baking soda inside the balloon using a funnel.
3. Stretch the mouth of the balloon over the top of the bottle (without spilling the contents) and use a rubber band to tie it around the bottle neck.
4. Pour the contents of the balloon inside the bottle. The balloon will slowly be inflated.

The reason is when adding baking soda in a solution of water and vinegar, a chemical reaction occurs that releases a large quantity of carbon dioxide, enough to inflate the balloon.

This is a simple and safe experiment to do with younger children but always be careful.
