Found this cool little recipe for Flubber. The children will love this stuff!
1/2 cup white Elmer’s glue
2/3 cup warm water
1 teaspoon Borax
2 glass bowls
In a small glass bowl, mix together glue, 1/3 cup warm water and food coloring (add enough drop until desired color). In another glass bowl, mix Borax and 1/3 cup warm water. Pour glue solution into bowl containing Borax mixture, gently stir together. It will be wet, and within a few minutes it will set.
