Polymer Experiments

So what is a polymer anyway? Well a polymer is simply a long chain of molecules that are connected. Lots of common items like balloons, paper, plastic bags, etc. are made up of polymers. When the pencil pushed into the bag, the pencil simply slid between the polymer chain. The polymer chains are held together around the ohld created by the pencil which prevents the water from leaking out.

Take it a step farther! What would happen if I pull the pencil out? How many pencils can I add? Does it mater if I use water or a different liquid? Does it have to be a pencil or can I use straws?
