St. Patty's day is a perfect excuse to make up some rainbow crayons. You might want to try and layer colors or just have a mod podge of color in your new crayons. During the summer you could use metal cans and if you live in one of those unfortunate hot spots melt your crayons outdoors to avoid heating up the oven.
What you need: broken crayons, old muffin tin or silicone cupcake liners you are willing to sacrifice, a source of heat, and a little time.
