Crayola Crayon Maker —
The Crayola Crayon Maker sounds like it would be great to recycle old crayons. My kids got one for Christmas last year and it drove us nuts. You have to set the timer, while the machine melts the crayon pieces in the molds. The molds tilt and fall and you can not stop the machine until the timer stops, which is 20 minutes. We tried it many times, and probably only got about 10 totally formed crayons. We gave it to a neighbor kid, who had the same problems as us. Save your money!
