Kid Science: Polymers
Polymers are groups of molecules that are connected to create a tangible object. Like plastic. The polymers in plastic are flexible, and actually move to form around a pencil poked through the bag to create a seal so that water doesn’t flow through. Try this experiment out to see polymers in action!
1. Pour water into a plastic bag.
2. Seal the bag.
3. Carefully push a sharp pencil through both sides of the bag.
4. When ready release the pencils over a bowl or sink.
