Flarp, flubber, slime, goo, gak, or oobleck. Whatever you call it, it’s fun stuff (if you’re a kid).
1 1/2 cups very warm water
2 cups Elmer’s glue
food coloring (optional, as could stain clothing and skin)
In a separate bowl, mix thoroughly:
1 1/3 cups very warm water
2 level teaspoons Borax
Mix the contents of the two bowls together kneading until it is fully combined. Discard any remaining liquid.
