This is a working playing mobile flamethrower trombone that has fire on demand (did it for fun). It is made up from plumbing, torch, and compressed air parts. It took about two weeks and a couple of weekends to complete. It has a fireball, and a concussion wave that can be felt. It can be difficult to play since it has a recoil and hits the player in the mouth. The gloves are for the cold tub
