Homemade playdough

Just thought I would share our newest find with you all.  I'm not able to be as active with my boys anymore so I went on a search of things that I could do with them.  This is perfect!  Very low energy, yet challenging for the kids and its practically free because you most likely have the ingredients in your pantry.  Can it get any better than that?  And it keeps my 4 year old quiet for more than 30 minuets!  Extra points for scoring me some quiet time.   I have some pictures of our creations, I will have to find them and post them.  But here's the recipe for now.

1c      all-purpose flour
1c      water
1/2c   salt
1T      cooking oil
3t       cream of tartar
food coloring

1.  Mix all ingredients in a pan
2. Cook on low heat, stirring frequently
3. When dough pulls away from the sides of the pan and begins to form a ball, its done.  Do not overcook.
