Eggshell Chalk

Supplies:

5 eggshells
1 teaspoon of flour
1 teaspoon of very hot water
food coloring
paper towels

Directions:

Crack open eggs and discard insides. Wash thoroughly in a pot with hot, soapy water. Drain water. Let dry. Dump eggshells into a bowl, grinding them into a powder and picking out large pieces. In another bowl, mix together the flower and hot water. Add a tablespoon of the eggshell mixture and mix together forming a paste. Add desired amount of food coloring, blending well. Shape powder mixture into chalk sticks. Use strips of paper towels to roll the chalk up in. Dry for 3 days until firm. Take out of paper towel. Use chalk on sidewalks. Not for chalk boards! Have fun!
