Summer Fun: Homemade Sidewalk Chalk

We are well into summer and we are finally getting to the “good stuff”. We’ve been consumed in other things which have caused us to neglect of summer to-do list. Now that things have calmed down a bit, we are frantically trying to do-all-the-things! One of the projects I’ve been wanting to tackle is homemade sidewalk chalk. Sure, you can get a tub of sidewalk chalk inexpensively at your nearest big box store, but there’s something more fulfilling and exciting making it at home. Kids always seem to have a better appreciation for basic simplicities that they’ve had a chance to create from start to finish. On the first days back to school, kids will be chattering about their summer days which may include writing on plenty of sidewalks, but how many of them will be raving about creating the chalk from scratch? Uh, yeah. This easy project equals instant cool kid and mom fodder.


Plaster of Paris
Tempera or Washable Paint
Silicon Mold or Tin Pan
Wax Paper if using tin pan
Disposable Bowls
Trash Bag to protect surface
(Find all these materials at Walmart.)

Cover work surface with trash bag. Line tin pan with wax paper sheets, cut to fit in each cell.

In each bowl, mix 1 cup Plaster of Paris, 1/2 cup water, and 3 tablespoons paint. Add more paint for a more bold color. Stir thoroughly until color is consistent. Be sure to work fast as Plaster of Paris starts to solidify pretty quickly.

Pour mixture in molds and let it dry overnight. Chalk can be removed by gently tugging at the wax paper. You may also use a small butter knife or similar to work around stubborn corners.

I’ll admit, I was a little nervous about this project, mixing powders and whatnot, but I am so pleased with the finish product. I whipped up this batch while Jayden was visiting with his great grandmother, so they were a surprise. The fact that Mommy made him chalk seemed to fascinate him so. We will be making another batch together since we have plenty of supplies left over.

How are you keeping the kids busy this summer? If you enjoyed this project, you may be interested in these summertime boredom busters!
