Balloon- hands free inflation

Here is a fun experiment to do... Blow up a Balloon without blowing into it!

• Pour 4 tablespoons of vinegar into a clean bottle.
• Use a funnel (it can be done with out but is messy) Fill a small balloon with 1 tablespoon baking soda
• Be sure the bulb of the balloon falls to one side as you carefully slip its mouth over the neck of the bottle

Lift the bulb of the balloon to let the baking soda fall into the bottle. The balloon will inflate all by itself.

Why it works:
When baking soda and vinegar come into contact, they form carbon dioxide. This gall fills the bottle and can't escape, so it rushes into the balloon, causing it to inflate.
