Homemade Play Dough

I need Play Dough for Tuesday. After talking to the school principal we learned we cannot put food coloring in homemade play dough, she's worried about the permanency of the the dye. Putting the food coloring in is the best part, but it's okay. We decided well pretend it's cookie dough and the kids can use cookie cutters to make "cookies." I found two recipes on Pintrest and decided to make them both.

Playdough:
1 Cup Flour
1/2 cup salt
2 tbsp oil
2 tsp cream of tarter
1 cup water
food coloring

Heat the oil in a pot. Remove from heat and add food coloring (if desired) and water. Stir in all other ingredients. Continue to cook over low heat until mixture is firm, about 4 to 5 minutes. Remove from heat, and set clay mixture on wax paper to cool. Store in an airtight container.

This is the second recipe I found. Homemade Play Dough- makes 2.5 cups.
1 1/2 cups of flour
3/4 cups of salt
1 1/2 cups water
1 TB vegetable oil
1/2 TB cream of tarter
food coloring (liquid kind)

Mix all the ingredients into a saucepan. Add the food coloring to your liking. - Children can help with this step.

Adults only-

Set your stove top to medium- low (about a 2.4 on a glass stove top). Stand by the pan and stir occasionally. When the batter look is gone and the ingredients start staying together when you stir (5-8 minutes), remove the pan from the heat. Lay out some wax paper and scoop play dough onto the wax paper. Once cooled, kneed the dough. Once the dough has been kneaded into a nice texture, place in an airtight container or zip lock.

Both of the recipes turned out about the same. The first one I notice is more grainy, but as far as softness I don't notice a difference. I am curious to see how they hold up after a few days!
