Make Your Own Chalk Stem Challenge

• Clean the eggshells and leave them to dry.

• Grind the eggshells in a pestle and mortar or electrical grinder. As long as you have a fine powder, you are good with either method.

• Place the eggshell in a bowl. Mix two tsp of plain flour and hot water to make a stiff paste.

• Add the food dye of your choice and then transfer the paste to a paper towel.

• Roll the paste into a tube, and leave it to dry for a few days.

• Your chalk is ready, and so is the artist in you!
