A fast project to make new crayons out of the old broken pieces you've got...
1- Seperate broken crayons from intact ones and take off paper.
2- Sort by color and put into foil cupcake holders so as not to ruin your pans.
3- Bake at 250 degrees for about 11 minutes. Do not stir them to keep the colors.
4- Let cool for 10 minutes.
5- Remove from pans and let cool for at least 6 hours to overnight.
6- You now have pretty new crayons for wee ones to play with!
