Rotary Snare Drum

What could be more irritating than a snare drum? How about a rotary, rapid-fire snare drum! It works by coupling a ratchet-type noisemaker to a drum-like membrane. It is both loud *and* obnoxious. Included are ratchets with different numbers of teeth, producing sounds ranging from a merely annoying rat-a-tat-tat to a head-splitting drone. Who thought up this #MakeItLoud challenge, anyway?
