Do not DIY: Homemade Tesla gun turns grown men into giggling fanboys

If you love videos that combine dangerous electrical experimentation, unique weaponry and great historical figures, then this video from Smarter Every Day is for you. This 11-minute video, which explores the genius of Nikola Tesla, culminates in a demonstration of a real, working Tesla gun, which is positively mesmerizing. It should go without saying, but don't try this at home. 

According to David Grossman for Popular Mechanics: "Telsa coils are electrical resonant transformer circuits, and they're the scientist's longest lasting legacy. They produce high-voltage, low-current, high frequency alternating-current electricity, and do so with style. As mentioned in the video, this is a DIY device straight out of Ghostbusters."
