Recycle those broken up crayons in minutes.
Peel off all paper and break into small pieces. Put a few pieces n each hole of a muffin tin. I used a mini muffin tin. Add enough to cover the bottom.
Pop in the oven at 300 degrees for 5 minutes or until melted. then throw them in the freezer for 10-15 minutes until set. Turn over and tap to remove them.
