Product Details

Wow! A gravity-defying demonstration that will stop students in their tracks! A beaker is filled with a 50-foot long string of beads. With just a slight pull on one end of the chain, the beads will suddenly lift themselves out of and come tumbling over the side of the upright beaker. This amazing feat mirrors the behavior of “self-siphoning” polymer gels such as polyethylene oxide. Use this highly visual demonstration to illustrate the structure of polymers. This low-cost demonstration may be used over and over again. It's sure to be a hit in your classroom! Teacher Demonstration Notes included. Concepts: Polymers, monomers. Time Required: 15 minutes Materials Provided: Polymer beads, 50-ft strand.
