Homemade Sidewak Chalk

Sidewalk chalk season is here!!  Start collecting toilet paper rolls, so you can make your own with your kids. Here is how:

You need:
Plaster of Paris
Disposable mixing containers
Disposable mixing utensil such as a Popsicle stick
Tempera Paint
Wax Paper
Duct tape
5-8 toilet paper rolls


Tape off the bottom of your toilet paper rolls with Duct tape nice and securely.  Then line the insides of the rolls with wax paper.  Place rolls on a wax paper lined baking dish, or cookie sheet.  Set aside.
Mix 1 cup Plaster of Paris to the ratio of water recommended on the box.  Mix in desired amount of tempera paint to reach your desired color.  A few tablespoons should do the trick.  Mix thoroughly.

Tip:  If you want a rainbow effect, or to make striped chalk, Allow the plaster to set a bit before pouring.  That way you can layer it easily.  For a swirl, layer the colors and then take a bamboo skewer and  run through the liquid plaster.
Pour the mix into the toilet paper rolls and let sit a few hours.  When plaster is hardened, peel the roll away from the chalk and continue to let dry a few days.  Throw used containers and mixers in the trash.  You don't want plaster clogging your drains. ;)
Now, go play some hopscotch with your kids!  So much fun!!!
