Homemade Playdough

I made this for the kids at Sunday school. I thought the kids would love this! I plan to make this for future gifts as it is super easy and not expensive.

4 cups of flour
1 cup of salt
2 heaping tbsps of Cream of Tarter
2 tbsp - 1/4 cup of oil
2-4 drops of food coloring
4 cups of boiling water

Add oil and food coloring to boiling water, then add to dry mix. Knead as soon as you can stand it, I used rubber gloves which helped! Keep kneading until it cools enough to solidify. Keep in an air tight container or plastic bag for up to 2 weeks, I think.
