lagerphone

noun1

1. •
   (Australia) A generally homemade percussion instrument consisting of crown cap beer bottle tops loosely nailed to a pole (often a broom handle) and a board mounted cross-ways on the pole (the head of the broom), and played by striking the pole on the ground or with a stick, by drawing the serrated stick across the pole, or by shaking the instrument.

   • In its modern form the lagerphone is of Australian origin and is a percussive instrument that produces a rhythmic effect similar to that of the tambourine. — 2003
