Hypothesis: If we stick a skewer through the balloon, then the balloon won't pop, because of the polymers holding tightly around the skewer that no air can get through. If we stick pencils through the bag full of water, then the water won't leak, because of the polymers holding tightly around the pencils not allowing water to get through the creases.
Note: First we are going to do this experiment on a smaller scale, using a plastic baggie and pencils.
Poke That Polymer!
A polymer is a really big molecule that links together with other polymer molecules to make a chain, which links up to more chains, and so on and so forth. This will make a polymer. Polymers are solid and used as plastics, and they can be molded into virtually any shape.
Question: Will the balloon pop when we stick a skewer through it?
Will the bag leak if we stick pencils through it?
Procedure:(for plastic bag)

The Science behind it
The Ziplock baggie and the balloon are made of a substance we use a lot of nowadays. It is polymer! Polymers are built in strands of tight molecules. When you poke a pencil into the bag full of water, the chains of molecules push around the pencil and prevent any sort of leakage. If you pull the pencil out, the chains break and it leaks. It is the same with the balloon, but the balloon is much scarier! If you pull the skewer out, it will deflate.
