Sure, you're not supposed to play with fire but what about painting with fire? That's what artist Steve Spazuk does. He uses flames and smoke to create beautiful artwork with images that are literally burned in. Spazuk employs other tools like feather brushes and x-acto knives but his artwork begins with fire. Pretty neat.

Here's a short on how he does it:
"For the past 14 years, Steve Spazuk has developed and perfected a unique technique that allows him to use the flame of a candle or the flame of a torch as a pencil to create his paintings with trails of soot. Using various tools, he intuitively sculpt the plumes of soot left behind in response to the shapes that appear on the canvas."
