Sidewalk Chalk
Ingredients:
2 cups water
2 cups plaster of Paris
2 tablespoons wet or dry tempera paint
toilet paper tubes
duct tape
Method:
Use duct tape to cover one end of each toilet paper tube. Mix all ingredients and set aside for 5 minutes. Line a cookie sheet with wax paper or foil. Place tubes upright on paper with open end facing up. You might want to tape the tubes upright onto the wax paper or foil to make it more steady. Pour mixture into holders. Leave standing until chalk mixture is almost firm. Rip off the toilet paper tubes and let the sidewalk chalk dry for about 2 more hours.
Eggshell Sidewalk Chalk
Ingredients:
4-5 eggshells
1 teaspoon flour
1 teaspoon very hot tap water
food coloring (optional)
Method:
Wash and dry eggshells, put in a bowl and grind into powder. Throw out any large pieces. Pour flour, hot water and 1 tablespoon of eggshell powder in another bowl. Mix until mixture looks like paste. Add food coloring now if you'd like. Shape and press the paste into the shape of chalk sticks. Roll up tightly in a strip of paper towel and allow to dry for about three days. Note: This chalk is only good for sidewalks.
