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 YouTube video to prove it.

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 against doing it themselves. Of course.

Bizarrely, instead of increasing in strength as the trombone is played, the fireball remains roughly the same intensity, with licks of flame jetting out from the trombone's bell.

But we're picking nits here. It's a trombone flamethrower. A flame-bone, if you will. Look on it, ye mighty, and despair, because music practice will never look as cool as this. Ever.
