The bazooka is a brass musical instrument that is several feet in length that has telescopic tubing like a trombone, but the bazooka resembles a vuvuzela. The radio comedian Bob Burns invented the bazooka in 1910 but it wasn’t popular until the 1930s when, many jazz musicians played the bazooka. From its start with a lipreed mouthpiece - which may consist of nothing but a bare tube or employ a mouthpiece which is handmade to emulate one from a low brass instrument - the air column expands into a wide length of pipe that slides freely around a narrower length of pipe, which, in turn, terminates the wildly flaring bell.
