My kids are playing with Gak! "What is Gak?" you ask. I found the recipe here. They are in absolute lala land. I added blue food coloring (1 drop) to his and red (to make pink) to hers. Try this with your little ones. The final mix should harden when you initially grab it and dissolve the tighter you hold it.
for this recipe you will need cornstarch, water and food coloring (optional)
4 parts cornstarch (see baking supplies dept. of supermarket)
1 part water
(Can add coloring.)
Add water gradually to cornstarch. Stir with fingers.
