Dig That Crazy Tesla Coil Sound

Giant Tesla Coils have been used on science fiction movies for about a hundred years now, but who knew they could be so musical?

Now two electrical engineering students (Eric Goodchild from ASU Polytechnic and Steve Caton from UCLA) found a way to modulate their 7 foot coils to play The Animals classic "House of the Rising Sun."

Each coil is capable of generating a 13 foot spark that equates to around 500,000 volts of electricity! The musical tones are made by varying the number of sparks per second, demonstrating a phenomenon known as electrical resonance.

Kids, don't try this at home (unless you're an EE, of course).
