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!
