SIDEWALK CHALK

1 cup plaster of paris
1-1½ cups of water
2 Tbsp. powdered tempera paint
Four 5-oz. waxed papers cups or one ice cube tray

In a plastic bowl, mix together the plaster of paris and the powdered tempera paint. Using a plastic spoon, slowly stir in the water until the mixture is smooth.

Half-fill each of the paper cups or the ice-cube tray sections. Allow the mixture to harden for one hour.

Peel away the cups or pop the chalks out of the ice-cube tray. Then allow the chalks to harden overnight.
