Sorry, this isn't a recipe that you would probably want to eat but it will keep the kiddos busy while you cook. So that counts, right? I think that I made this about every single day when we moved to PA and needed to unpack boxes. The Lukester thought it was the greatest thing ever. Easy and cheap and you've got to love that fun cornstarch texture.
In container add 1/4 cup cornstarch, then 1/4 cup water, about 5-10 drops of food coloring. It might be difficult to mix at first, but it will suddenly come together (remember to put cornstarch in container first).
Grab some paintbrushes and enjoy painting before it gets too chilly!
