Recipe Introduction
This chalk is for drawing on sidewalks only, not for chalkboards.
List of Ingredients
The shells of 6 eggs
1 t very hot water from the tap
1 t flour
Recipe
Wash the eggshells well, so they don't have any egg left in them. Dry
them and grind them with a rock on the sidewalk or other concrete surface.
Make sure the rock you're using for grinding is clean so you don't get dirt
ground in with the eggshells. Grind the eggshells into a fine powder. You'll
need one soupspoonful of this powder to make a stick of chalk.
When you have enough powder to make a stick of chalk, sift or pick out any
little bits of eggshell that are still not ground up and throw them away.
Scoop the powder into a cup or paper towel and bring it into the house for
the next part. Stir the flour and hot water together in a small dish to make
a paste. Put the soup spoonful of eggshell powder into the paste and mix
well. It may help to mash it with the back of the spoon. Add a few drops of
food coloring if you want colored chalk. Shape this mixture into a chalk
stick.
Then roll it up in a strip of paper towel and set aside to dry. (Drying
takes about three days.) Then just peel the paper off one end and you're
ready for some sidewalk art. For really big sticks of chalk, try making 3
times this recipe, and stuff the mixture into an old toilet paper tube. When
it's dry, you can peel away the cardboard as you use it.
