Children’s Sidewalk Chalk
3/4 cup warm water
Toilet tissue tubes
1 1/2 cups plaster of Paris
2 to 3 tablespoons powdered Tempera paints
Container for mixing
Cover one end of tissue tube with duct tape. Place a loosely rolled piece of wax paper into the tube to create a liner to keep the plaster from sticking to the tube.
Pour water into mixing container then sprinkle plaster, a little at a time, into the water until plaster no longer dissolves (approximately 1 1/2 cups). Stir thoroughly. Mix in 2 to 3 tablespoons Tempera paint.
Place tubes sealed end down on a flat surface. Pour plaster mix in. Tap side of tube to release air bubbles. Let dry 1 to 2 days, pull off mold and have fun drawing!
Be sure to rinse container and spoon outside or in a container of water to avoid clogging indoor sink drains.
