Make Your Own Sidewalk Chalk

Print Friendly, PDF & Email

Learn how to make big chalk sticks using a few simple ingredients.

What You Need:

  • 1 cup of plaster of Paris
  • 1/2 cup of cold water
  • Candy or Popsicle┬« Molds OR empty toilet paper rolls
  • wax paper
  • Tempera Paint (powdered is best)

What You Do:

Combine Plaster of Paris, water and tempera paint. The amount of tempera you add will determine how dark the colored chalk will be.

Line your molds with wax paper.

Pour the mixture into molds and let dry.

Take the chalk out of molds and use for drawing on the sidewalk.

This chalk will be most effective right after taking out of the molds.

Added Tip:

I used your chalk recipe. Kids were very impressed. Beside using dry tempera, I added a small amount of acrylic craft paint for color and it worked great. We tried using paper coin tubes but found that difficult and messy. We did find that a toilet paper tube worked well or a 5 oz. Dixie® cup.
