Tesla coils seen wowing onlookers, cooking hot dogs

Believe it or not, tesla coils are good for more than just creating lighting, protecting one's laptop or cranking out a sweet tune -- and the folks watching a dazzling demonstration at Maker Faire 2008 can attest to that. Apparently a group of prototype (1 / 12 scale, no less) coils were seen sparking up the evening in San Mateo, California, but it wasn't the visual energy or unmistakable hum that caused all that saliva to form in the mouths of onlookers. Oh no, it was the fact that a dozen hot dogs were simultaneously roasted and made ready for safe consumption. Check out a video of the action right after the break.
