Eggcelent Entertainment

Adults must operate the food processor, do not attempt to do this experiment alone!

1. Wash the eggshells and remove any access yolk/white. Dry the shells and grind them into a fine powder using a food processor or a mortar and pestle. You will use one tablespoonful of this powder per stick of chalk.

2. Measure the powder. When you have enough powder to make a stick of chalk (1 tablespoon) sift or pick out any little bits of eggshell to ensure the powder is clean and clear.

3. Stir the flour and hot water together and make a paste. Put the tablespoonful of eggshell powder into the paste and mix well. Add a few drops of your food coloring.

4. Shape this mixture into small chalk sticks, Then roll it up in a strip of paper towel or other absorbent material and set aside to dry for one to three days. Once dried, peel the paper and draw!
