Pop or No Pop Magic!
What will happen when you stick a pencil through a plastic bag full of water?
Hypothesis
We think the pencil will pop the bag and the water will leak out through the holes.
Procedure:

Conclusion:
In conclusion, our hypothesis was wrong. The bag of water with the pencils stuck through it does not leak because the bag is made out of polymers.
The Science behind the Magic:
Polymers are a chain of molecules which are flexible and tough. The polymers hug around the sides of the pencils, creating a water-tight seal preventing any water from leaking out of the bag. With the Leak-Proof Bag experiment, the objective of this experiment is to show that plastic has a lot of properties and that it is very stretchy. The secret isn't magic, it's just the chemistry of polymers.
