Get this- I used Kool-aid mix to made play-doh. And it smells delicious!
Mix/whisk together in a large bowl:
2.5 cups flour
1/2 cup salt
2 pkgs unsweetened kool-aid (choose according to what color you want)
Add 2 cups of boiling water and and 3 tbsp oil to the dry mix with a wooden spoon. stir quickly as it cools. Mix with hands as needed. Store in an airtight container. Its that easy!
