Vortex Shedding in Air

Описание к видео Vortex Shedding in Air

A thin wire, moving through the air, is made to vibrate in the audio range at the vortex shedding frequency. Power lines and other tension wires "sing" on windy days because of this same phenomenon. Here, instead of the air moving past the wire, we got the wire to move past the air!
