Eggshell Sidewalk Chalk is a great way to use up those leftover eggshells from Easter Eggs! Your kids will love helping you make these.

If you already have colored eggs, don’t fret, this won’t affect the quality of your homemade eggshell sidewalk chalk in any way. In fact, it’ll add a touch more color!

Now, we mention that this recipe is to repurpose eggshells. Generally speaking, to make the best quality chalk you’ll want to use shells off hard-boiled eggs.

If you’d prefer to repurpose eggshells from another recipe, such eggs used in an omelet, you’ll need to boil them first (or your chalk will smell bad after a day or so!). Once they’ve been boiled, you can rapidly dry them by placing the drained shells onto a dry paper towel and heating them in the microwave for about 4 minutes.


You’ll Need
5-6 eggshells- powdered (use a blender)
1 teaspoon flour
1 teaspoon very hot tap water
2-3 food coloring of your choice (optional)


Pour flour, hot water and 1 tablespoon of eggshell powder into a small bowl, mixing until paste forms. Add food coloring now, if desired.

Shape and press the paste into the shape of chalk sticks, water bottle ice cube trays make the PERFECT sized chalk stick, or Roll up tightly in a strip of paper towel and allow to dry for about three days.

Note: This chalk is only good for sidewalks, do not use on chalkboards.
