Play Dough

I remember using this recipe to make 4-5 different colors of play dough to make the earth and the different layers (inner core, outer core, mantle and crust) there for a science project in elementary school. My mom was pretty amazing. We just use it to play with and come up with all sorts of great colors.

1 C. Water
2 Tbsp. Oil
1/2 tsp. Salt
1 C. Flour
2 tsp. Cream of Tarter

combine all ingredients over medium heat until it sticks in a ball, you can add food coloring as desired. Keep in a Ziplock bag for re-use over and over.
