Sorry about the title but I couldn’t resist. Hack a Day has a little post up on how you can make your own Jacobs Ladder, which is that crazy thing you see at museums with the electricity shooting up between two metal poles. Basically, you just have to get your hands on a high voltage transformer, such as one found in a neon sign. Add a set of two insulated electrodes (aka metal poles) and wire it all up. Boom. You’ve got electricity shooting all over the place.
Don’t kill yourself or the dog. Please?
