PFS - Sidewalk chalkAhhhh spring!  Spring brings a different set of outdoor activities to enjoy: 4-Square, hopscotch, ball hockey, marbles, tirar frijoles, circle tag.  Make sure you are ready with your custom made sidewalk chalk.

Supplies needed:

  • Toilet paper tube
  • Small square waxed paper
  • Rubber band
  • Recyclable/Disposable plastic container (e.g., deli container)
  • Craft stick

  • Plaster of paris
  • Corn starch
  • Tempera paint (Optional)
  • Water

Secure a double thick piece of waxed paper at the end of a toilet paper tube with the rubber band.

In the plastic container mix ½ cup plaster of paris and ¼ cup corn starch. Slowly add ¼ to ½ cup water while stirring with the craft stick.  Add tempera paint until the desired color is achieved.

Put mixture into prepared toilet paper tube.  Set the tube upright (waxed paper side down) on a plastic lid or newspaper until it hardens – generally overnight.  Once it hardens/dries, peel off the paper tube.  It is now ready to use!

IMPORTANT: Do NOT rinse cup in the sink!!  This stuff hardens and will clog sink!
