In case it's still not clear, it's art. Made from melting crayons. (You're welcome.)
Honestly, it's not something I plan on doing anytime soon. I'm not very crafty and the project screams messy. I prefer my crayons safe in their box and, in a perfect world, snug tight with their color family and nicely sharpened.
But, if it's something that you would like to try, a child shows you how to do it below. If a child can do it, I could if I wanted to. Probably.
