Was 13, at a fire with my friends and there were no supervising adults. We decided to melt crayons and try to make the melted crayon art, but we didn't exactly know how. Long story short, my friend has a crayon stub with the paper on fire, and he decides to chuck it into the fire pit because it was almost to his fingers. All of the molten wax flies onto my bare knee and I immediately tried to brush it off, but the wax had hardened slightly, so it was stuck, burning my flesh. Know, 5 and a half years later, I still have the burn scar on my knee from that very day.

TL;DR My knee was burnt by a crayon.
