blow up your own balloons, minus the helium

My little guy loves to experiment and he loves to play with balloons.  So why not experiment with a balloon?

What You Need:

baking soda

vinegar

plastic bottle

balloon

2 funnels

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 before you are ready for it to expand.

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
