Sidewalk Chalk
What You Need:
- Two cups water
- Two cups plaster of Paris
- Two tablespoons wet or dry tempera paint
- Toilet paper tubes
- Duct tape
What You Do:
- 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 (open end up) on cookie sheet. Tape the tubes upright onto the wax paper or foil to make it steadier. Pour mixture into holders. Let sit until chalk mixture is almost firm. Rip off the toilet paper tubes and let the sidewalk chalk dry for about 2 more hours.
