Sidewalk Chalk (Original Author Unknown)
Need: toilet paper tubes
3/4 cup warm water
about 1-1/2 cup plaster of paris
2 to 3 tsp powder tempera paint
Directions: Begin by making a mold for the homemade chalk. Cover one end of the tissue tube with duct tape. loosely roll up a piece of wax paper and slip it into the tube this lining will keep the plaster from sticking to the mold. Pour the warm water into a disposable plastic container sprinkle in the plaster of paris a little at a time, until the powder no longer dissolves (about twice as much plaster as water). Stir thoroughly with a spoon. Then, mix in the tempera paint. For pastel shades, combine white tempera with a primary hue. Rinse your spoon under an outdoor faucet to avoid clogging drains. Place the mold sealed end down on level surface and pour it into the wet plaster. Lightly tap the sides of the tube to release air bubble in the plaster. Let the chalk harden a couple of days. Then, remove the tape and slide the marking stick out of the mold.
