1 cup plaster of Paris ½ cup cool water 2-3 tablespoons of Biocolor or tempera paint
Mix 1/3 cup of the cool water with the paint
Pour plaster into a disposable container
Using a disposable stirring stick, pour paint/water mixture into plaster
Stir well, especially at the bottom of the container (Colors will darken as they dry.)
Add just enough water to wet all of the plaster
Stir well and pour into molds
Suggested molds: 3 oz/5 oz Dixie cups, Novelty ice cube trays, or any mold that will not leak and will release easily.
Chalk will set in about 30-40 minutes. Then release from molds and let stand for 24 hours. (Leave chalk in Dixie cups to cure.)
Never pour in the sink!!! Pour out the little you have extra into something that you can throw away or onto newspaper.

Eggshell Chalk
4-5 Eggshells
1 tsp. Flour
1 tsp. very hot tap Water
Food coloring, optional
Wash & dry eggshells. Put into bowl and grind into a powder. A mortar and pestle works fine for this.
Discard any large pieces. Place flour and hot water in another bowl and add 1-tablespoon eggshell powder & mix until a paste forms. Add food coloring if desired. Shape & press mixture firmly into the shape of a chalk stick. Roll up tightly in a strip of paper towel. Allow drying approximately 3 days until hard. Remove paper towel & you've got chalk! Eggshell chalk is for sidewalks only.
Kids of all ages love playing with chalk. They can be creative and the clean up is a snap. For an interesting twist that is great for Easter or it can just make it easier for little hands to grasp, all you need is an egg carton and some fillable plastic eggs.
First coat the inside of the plastic egg halves with Vaseline. Then place the halves into the egg carton to hold in place. After you have the mixture ready pour into the egg halves. let the chalk set up for about 5 minutes. Then carefully place the tops on the bottoms. Give the egg a little shake and then tap the top to get air bubbles out. Let them harden over night in the egg carton. To remove, carefully pull apart the egg by twisting the sides opposite directions.
These would be great in an Easter basket or for an egg hunt. You can also use this method to make dinosaur eggs and have an egg hunt at a dinosaur themed party. Let the kids take them home as great homemade party favors.
