Mix together in Bowl #1:
*2 cups white glue
*2 cups water
Mix together in Bowl #2:
*1 1/3 cup warm water
*1/3 cup plus 1tsp. Borax (20 Mule Team Borax laundry detergent)
Slowly pour Bowl #2 into Bowl #1 (approx. 1/3 at a time) After each 1/3 poured, pull out a blob of flubber from Bowl#1 and set it aside. When entirely mixed, knead to get out excess water.
I didn't see the measuring of our flubber but I think they put too much water in. It did become more bouncy and less messy when they poured the excess liquid off. Now the question is: will it ever come off our driveway?
