Balloon Expansion with Baking Soda and Vinegar
Question: Does baking soda and vinegar create carbon dioxide?
Hypothesis:
Our hypothesis is that mixing vinegar and baking soda will create co2 which will expand the balloon.
Procedure:1. Place about 1/4 cup of vinegar in the bottle, using a funnel if needed. 2. Place 1/2 teaspoon of baking soda inside the balloon using funnel if needed. 3. Attach the balloon to the top of the bottle, taking care to keep to keep the balloon hanging down from the side of the bottle. 4. Quickly raise the balloon over the bottle and shake the baking soda down the balloon |

The Science behind it
The balloon should expand due to the reaction of the vinegar and baking soda to make carbon dioxide. The pressure of co2 gas produced is enough to blow up the balloon.
Conclusion
Basically mixing vinegar and baking soda will create co2 which will expand the balloon.
