Sun Melted recycled crayons ~ I am going to try using the cookie cutters in the oven instead of a mold. I have tons of cookie cutters. On the next hot day I will try using solar power to do the melting!
Melted crayon hearts: A boy in my class a couple years ago gave these as little Valentines made out of melted crayons. He said, "For Crayon Out Loud, Happy Valentine's Day". could also say, "You COLOR my world!" Use silicone cups to melt them in.
