Steve Spangler Science: The Leakproof Bag

Polymer chains work together to prevent water from leaking out of a bag.

Who would have ever thought that a plastic bag, some water, and a few pencils would have adults screaming with fear? learn how to poke holes in a plastic bag filled with water without spilling a drop. Well, that’s the theory you’re going to test . . . and it’s wise to practice your liquid trick over the sink. It’s a cool way to learn about the chemistry of polymers.
