Homemade Sidewalk Chalk - cooking recipe

Ingredients

1 cup plaster of paris
1/2 cup cool water
3 tablespoons liquid powdered tempura paints

Preparation

Pour plaster into a clean container (like a coffee tin or ice cream tub).
Using a disposable stir-stick, stir in most, but NOT all, of the water.
Add 2 tbsp of the liquid tempera paint, mixing well, especially at the bottom; add another tbsp of paint if you think it needs it.
Add a little more water as the mixture thickens.
Stir well and pour into small containers, such as the tiny dixie paper cups.
Peel paper off after the chalk dries, give to the kids, and let them have fun; outside, of course!
