You guys are tough
I think maybe he was talking about putting 9volts through a transformer and touching the other end. My uncle built something like this and went around with a button on it shocking people for kicks....yeah he was a little odd.. Let me tell you, touching the other side of that transformer REALLY could knock you. It takes a lot of current out of the battery all at once and multiples it. It's mainly the current that kills you. If you had a weak heart and the shock was a longer duration, yeah you might be pushing up daiseys. Those things the cops use for crowd control, they don't use a lot of voltage either, but they will shock the piss out of you. If you really want some excitement in your life just piss on an electrified cow fence..............don't ask me how I know that.
