Instead of using glue as a polymer (as in the slime recipes above), we're going to use PVA (polyvinyl alcohol). Most liquids are unconnected molecules bouncing around. Monomers (single molecules) flow very easily and don't clump together. When you link up monomers into longer segments, you form polymers (long chains of molecules).

Polymers don't flow very easily at all - they tend to get tangled up until you add the cross-linking agent, which buddies up the different segments of the molecule chains together into a climbing-rope design.

    PVA and Borax can be very irritating to your eyes. It is best not to touch this slime. But if you do, be sure to wash your hands with soap and water after you finish your experiment.

  2. Hi.Its Maudie and I would like to now if you can touch the PVA SLIME. I noticed you only used a
    popsicle stick. You’re a GREAT teacher.

    Love,Maudie
