Oh yeah- got to watch someone who was unsure of the concept once. Fortunately, this was outside. He put wax in a can over a live flame. It did melt. It also eventually ignited.

The best part was when he through water on it. The steam explosion threw a wonderful, mushroom-like fireball about 12 feet in the air. :P

I did warn him.
