Really. This guy built a Tesla Coil. Not sure exactly why, but being someone who's always had weird issues with thunderstorms/lightning/tornadoes, this is strangely fascinating.
I'm not sure if they show it on this video but on one I saw they show the guy's checklist of what he double checks before turning it on and one of the items is "dogs inside". I'm glad he's not electrocuting his dogs with his lightning machine.
