Once you have a substantial collection of broken or worn down crayons, you can create unique multi-colored crayons to enjoy. Preheat the oven to about 275 degrees, and peel the wrappers from all the crayons. If there are any pieces that are still fairly large break them down a bit.
Place empty cupcake liners on a rimmed cookie sheet. Fill them a bit less than half full. You can use complimentary colors, crazy combinations, or even all the same color if you want. Bake for approximately ten minutes or until all the crayons have melted together. Be sure not to let the mixture come to a boil or the colors may combine instead of creating a multi-colored effect. Once the crayons have melted carefully remove from the oven and allow to cool for about an hour. Then peel the paper liner off and enjoy your new creation!
