Nothing screams outside fun like SIDEWALK CHALK! Our little Rembrandt's go through BUCKETS FULL each summer. Here's a fun activity to do as a family that helps keep your CHALK supply plentiful! It's cheap, easy to make and a great science project! The sidewalk is their blank canvas--let them create!
What you will need:
• Toilet paper or paper towel tubes(cut paper towel tubes in 1/2)
• Scissors
• Duct tape
• Wax paper
• Small bucket or disposable container to make the recipe
• ¾ cup of warm water
• 1 ½ cups Plaster of Paris
• 2-3 tablespoons of tempera paint
Step 1: Cover end of each tube with duct tape. Line each with waxed paper. Stand tubes on end within a container nice and snug similar to bowling pins. (Duct tape side goes on bottom.) 
Step 2: Follow directions to begin
making Plaster of Paris.
(Monitor your children for safety- it hardens
in 20-30 minutes! Work fast.)
Step 3: Pour the tempera paint into the Plaster of Paris mixture and stir so that it is mixed thoroughly.
Use separate containers to
create the varying colors.
Step 4: Spoon your colored chalk mixture into the wax paper lined tubes. Give each tube a tap to release air bubbles!
Step 5: Set the chalk aside to dry. It might take a good 3 days or so.
