Flubber 

Flubber (aka "Gluep") is a fun material to make for children from 5 - 16 years of age.  Children can experiment with different recipes to make the flubber have different physical properties.  Flubber  is a polymer or plastic-like material.  It is the product of cross-linking polyvinyl acetate together.   

Slime can be produced by combining 3% polyvinyl alcohol (PVA) solution with 3 % borax solution.  Clear Elmer's glue is PVA .  My recipe uses 1 cup PVA glue with 1 cup water.  The borax solution is 1 tablespoon borax detergent in 1 cup warm water.  Slime will be clear and less viscous (more runny) than flubber.

Materials:

    In a large container combine:

    In a second container, combine:

Mix each container thoroughly.

Pour contents of smaller into larger.

Gently lift and mix with a metal spoon until a Tablespoon of liquid remains.

Let excess liquid dry off - wait a few minutes and FLUBBER will be ready.
