According to the guy in this video, he's not the only person who thought to modify their trombone to spit fire. He says he got the idea to build a flamethrowing trombone from other user-made videos on the Internet. After about two weeks of work he had a brass instrument that could still belt out a tune and shoot fireballs 21 feet thanks to "compressed air parts" and a torch. Why on earth would you need or want a fire-shooting trombone is beyond us, but it's cool as hell.
