Here's the recipe if anyone is interested:
2 1/2 C Flour
1/2 C Salt
1 T baby powder
3 T oil
2 packets Kool-aid - the ones without sugar added, any flavor
1 1/2 C boiling water
Stir all ingredients together. You'll have to keep adding more flour (sometimes more than a cup) until the playdough is no longer sticky.
