homemade play dough

I saw a list of fun things to do in the summer time that's cheap. I read them off to the kids. One of the things is to make play dough. Wyatt bugged me for days until we made it. The boys picked out the color and it was way easier than I thought. I should have made it the first day. All it is:
2 cups flour,
1 cup salt,
3/4 cup water,
2 tablespoons cooking oil,
food coloring.
If you want to make a lot stock up on the salt. I was reading on another blog that they used Koolaid to make it smell better. You'll have to try it.
