Balloon Fun

The recent trip to Chemfest has inspired us to play with balloons! The girls have been blowing them up and letting them fly around, or using them to make funny noises by stretching the opening while letting the air out.

They also taped balloons to matchbox cars, blew up the balloons, and let them go. The air from the balloons pushed the car. They loved it.

We also used the chemical reaction of vinegar and baking soda to blow up a balloon. We poured some vinegar in an empty bottle. Then we put baking soda inside the balloon with a funnel.

Then we stretched the balloon over the opening of the bottle with the vinegar.

Then we tipped the balloon up to let the baking soda fall into the bottle.

Then we had a balloon filled with carbon dioxide.

Here's another one we want to try: http://www.weatherwizkids.com/balloon2.htm
