Question
Can you inflate a balloon without using your mouth?

3. purpose
The purpose of this project is to observe the chemical activity of mixing baking soda with vinegar. Students learn about gas and chemical reactions by discovering how to inflate a balloon using baking soda and vinegar. The goal of the project is to demonstrate the power of gas produced when baking soda and vinegar are mixed. The goal is for the balloon to be blown up by the gas created.

4. Hypothesis
I believe that you can inflate a balloon without using your mouth because there are certain chemicals that may cause such inflation.

5. Baking soda Empty soda bottle Vinegar Balloon Straw or a funnel
Materials
Baking soda
Empty soda bottle
Vinegar
Balloon
Straw or a funnel

6. Procedures
Place two teaspoons of baking soda into the empty pop bottle
Add an inch of water in the bottle
Next, place a tablespoon of vinegar into the balloon
Put 1tbs., 3 tbs., and 5 tbs. in three different balloons.
Cover the top of the bottle with the mouth of the balloon.
When the balloon is on correctly, lift the end of the balloon releasing the vinegar into the bottle where the baking soda and water waits
Watch what happens
Does the balloon expand? Does the balloon shrink?

7. Observation
With 1 tablespoon of baking soda, the balloon inflated very little. With the 3 tablespoons of baking soda, the balloon inflated a lot more. With the 5 tablespoons of baking soda, the balloon inflated a lot more and some balloons popped off the bottle.

8. DATA Substances Results Vinegar with 1 Tablespoons
Balloon inflates a little
Vinegar with 3 Tablespoons
Balloon inflates a lot
Vinegar with 5 Tablespoons
Balloon inflates and pops off the bottle

9. Conclusion
My conclusion was correct! You can inflate a balloon without the use of your mouth. Why? Because when the vinegar reaches the baking soda, a chemical reaction takes place. During this reaction carbon dioxide is formed. This gas is released from its liquid/solid state which makes the balloon expand. See how large you can make the balloon by adding more baking soda, vinegar, and water.
