We liked making and playing with the OOBLECK so much, that I searched around for something similar.
This time we made GAK.
It's just 3 ingredients and not as messy as the oobleck.
I'm sure we'll make it again.
I even let the 2 year old play with it... outside that is.
1 cup Elmer's glue
Food coloring (optional)
1 cup liquid starch (found near the spray starch & laundry detergent)
Mix glue and food coloring in a plastic container.
Add the liquid starch a little at a time. You can stir with your fingers or with a spoon.
Soon, the mixture will resemble putty.
If it's too sticky, just add a little more starch until it's a nice rubbery consistency.
