Fire!

Ok, to get the disclaimers out of the way, playing with fire is dangerous.

You should not try any fire stunt without a spotter, safety equipment, instruction and training.

Equipment could fail if you build it improperly, and could injure yourself or your audience.

Even with proper tools, even profesionals can get burned. So be careful!
