Melted Crayon Painting

Buzz feed lists a lot of ways to use crayons and a hair dryer for a really neat effect but the one that's most different is using up all of those little crayon pieces to create something new.  Kids will have as much fun smashing up the crayons and designing them on the page as they will melting them.
