With the 4th of July approaching, our minds turn to gadgets with lots of pyrotechnics. We recently saw a news story on MSNBC about the Frankenhorn Flamethrower Trombone. The horn has been modified with a torch and compressed air mechanism so that it now generates a 21-foot fiery blast of sound with a concussion wave of 150 feet. The trombone can still be played, but it has a mean recoil.
