Giant Sidewalk Chalks
(Do not use on chalk boards)
- ¾ cups of hot water (but not boiling water)
- Empty toilet paper rolls Approx: 1 ½ cups of plaster Paris
- 2 or 3 tablespoons of food coloring or poster paint
- Waxed paper
- Wide adhesive tape
- Plastic container for mixing
- Cover one end of each of the toilet paper rolls with adhesive tape.
- Line the interior of the tubes with waxed paper to prevent the plaster from sticking to the sides.
- Pour the water into the plastic container and add the plaster Paris while mixing with the spoon. Add a small quantity at a time until the plaster no longer dissolves in the water.
- Mix thoroughly until a creamy texture is obtained. Add the paint or food coloring. Stir until the mixture is homogenous.
- Place the tubes, closed ends downwards, on a flat surface. Pour plaster into each tube. Tap the sides of the tubes to prevent air bubbles (which would result in holes in the chalk).
- Allow to dry for a day or two. Peel off the mould and use on asphalt or concrete. The chalk washes away easily with rain or running water.
