Solid or Liquid?

THE ACTIVITY: FLUBBER!
Using glue, water and a 'magic' solution of water and Borax. We turned a liquid into a solid*. It all happened right there, before our very eyes, in our own hands. This richly tactile activity is always a favorite, providing hours and hours of classroom enjoyment and stimulating brain development.

*Based on the simple definition of a solid as something you can pick up with your hands. In reality, Flubber is classified as a 'Non-Newtonian Fluid', possessing properties of both a liquid and a solid. You can pick it up, yet it will very slowly pour and return to a puddle-like form when left alone.
