The Absent-Minded Professor
Flubber (named from the film "The Absent-Minded Professor"), Glorp, Glurch, or Slime are common names referring to a rubbery polymer formed by cross-linking of polyvinyl alcohol (PVA) with a boron compound. Flubber can be made by combining polyvinyl-acetate-based adhesives such as Elmer's Glue with baking soda, borax, and (optionally) shaving cream as an elementary science education experiment.
