There's no need to offer a "Don't try this at home" warning — by the time you've watched this guy accidentally shock, burn, and shoot himself, you're unlikely to follow in his footsteps.

It might seem a little strange to talk about making guns so soon after that botched assassination attempt in Bulgaria, but this homemade rail gun is even less likely to work when you need it to. Mad scientist Mehdi Sadaghdar walks us through all the mistakes we'd inevitably make if we were dumb enough to try this ourselves, and throws in a little unibrow dancing for good measure. Now that's science education!
