Eggshell Chalk

How can we reuse cracked eggshells instead of throwing them out? Some people compost them for their garden, but did you know we can turn them into art supplies?

Materials:

• at least 6 eggshells

• 1 tsp very hot water

• flour

• food coloring

Instructions:

1. Wash the eggshells so there is no longer egg on them! Dry them and grind them into a fine powder. Maybe your house has a mortor and pestle for grinding, or you can use a rock on a hard, smooth surface. About 6 egg shells per stick of chalk.

2. Sift or pick out the big pieces of eggshell that are not ground up. Put the powder into a cup.

3. Add a teaspoon of hot water and stir the shell powder until it makes a paste. Add food coloring or paint if you like color!

4. Shape this mixture into a chalk stick. Now roll it in a strip of paper towel and let it dry. This may take up to three days. Peel the paper off and you're ready for some chalk art!
