Sidewalk Chalk

1. 1

   To make white chalk:

2. 2

   Mix together plaster of Paris and water until the mix is about as thick as toothpaste or mashed potatoes. (If it seems too runny, add 1 tablespoon of plaster at a time until it's thick enough.

3. 3

   If it seems too thick, add a small amount of water.)

4. 4

   Set the cardboard tube upright on the waxed paper.

5. 5

   Spoon the mix into the tube.

6. 6

   Try to pop or push out any bubbles.

7. 7

   Let the filled tube rest upright on the waxed paper for 3 to 4 hours until the chalk has set.

8. 8

   Then, peel off the cardboard (it will be damp).

9. 9

   Let the chalk dry completely for 24 hours.
