Then we mixed some corn starch and food coloring and water, which only Bastian played much with.
Finally, everyone was thoroughly impressed with the slime recipe.
1 qt. of water
1/4 cup Borax
1 Cup Elmer's glue
1 Cup water
In 2 separate containers: Disolve the Borax in 1 qt. water. Dissolve the glue in 1 Cup water.
Mix 2T Borax solution with 6 T glue solution. (Any 1:3 amount will work, of course.)
If you want to make different colors, add food coloring to the glue mixture. You can save this in a baggie.
