Can you inflate a balloon without
using your mouth?
QUESTION
PURPOSE
To observe the chemical activity of mixing baking soda
with vinegar.
HYPOTHESIS
I believe that you can inflate a
balloon without using your mouth because there are certain chemicals that may cause such inflation.
MATERIALS Baking soda Empty soda bottle Vinegar BalloonStraw or a funnel
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?
OBSERVATIONWith 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.
DATASubstances 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
CONCLUSIONMy 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.
