Pyro's Flamethrower Trombone

Ever taken a bottle of propane, attached it to a trombone and then used it as a flamethrower? Jonathon Crawford has, and he's got a video of him using it online to prove it.

Though we do not in any way encourage anyone to do anything like this, ever, but as Mr. Crawford has, we thought we ought to share. You know, to warn people from doing it themselves. Of course.
