When crayons break or crack into bits, your first inclination is to throw those pesky pieces away before they end up between the couch cushions or in someone's mouth.
Instead of trashing them, melt them into rainbow crayons that your kiddos will love. Just take the left over crayons and peel the paper off of them. Line a muffin pan with foil cupcake wrappers. Place a few chunks of the crayons in the muffin pods and put the pan in the oven for a few minutes on low heat (about 250 degrees). Pull them out once the colors have melted and let the new rainbow wheels of wax cool off overnight. Once cooled off, peel the cupcake wrappers off the crayon wheels.
Your kids will love the new invention — they are especially great for rubbing images.
