The picture above shows a cordless drill a man modded into a little handheld Tesla Coil. As is evident from the picture, the little coil is great for things like, um, making a light bulb glow like a plasma globe. Neat buddy, but can you mod a cordless drill to put holes in wood and other objects? Because that, my friend, would be frickin' sweeeeeet.
Video of the coil in action after the shock.
