What is going on?
Mixing vinegar and baking soda together creates what is called a chemical reaction. Chemical reactions can be identified by one or more of these three basic indicators;
As you lift the balloon causing the baking soda to mix with the vinegar, you can see the chemical reaction taking place. This reaction is actually creating carbon dioxide gas. By placing a balloon over the mouth of the bottle, we are able to capture the gas that is created during this chemical reaction. The production of this gas is what causes the balloon to be inflated.
Try adjusting the amount of vinegar and baking soda to see how big you can make your balloon. Be aware that by adding too much may cause the balloon to pop which could make quite a mess! Wear eye protection just in case! You don’t want any of this in your eyes!
You can also try placing a balloon over the mouth of a bottle of club soda. See how big the balloon will get as the carbon dioxide gas is released from the club soda. Does the balloon get bigger if you shake the bottle?
Try putting pop rocks in a bottle of club soda and placing a balloon over it. Is there any difference with the pop rocks versus just using club soda?
More information regarding the exploding Pringles can on air:
Since I didn’t do a very good job explaining this on air, I wanted to take a minute to explain it here. When I ignited the hydrogen gas, oxygen was being drawn into the can as the gas was burnt. It usually takes less than a minute or so for the hydrogen gas to be consumed to a point where there is a mixture of hydrogen and oxygen that will cause the flame to burn down into the can causing the violent explosion, sending the can up into the air. DO NOT TRY THIS AT HOME !!! There are specific details about this experiment that make this experiment work the way it did which I will not share as we do not want anyone to get hurt. Attempting this experiment yourself can be extremely dangerous. Do not attempt this experiment.
