This is how to modify a disposable camera to redirect the voltage that would normally be used to charge the capacitor to shock the unsuspecting user instead. I actually saw some kids do this in middle school a long time ago, but all they did was take the camera apart and take the two wires and twist them so that they were crossed but not touching. Then they'd slap you on the arm with it and they'd connect and shock. It was ghetto, and I'm pretty sure those kids have long since gotten their first taste of prison food. Anyways, this version is a lot classier than that one. There's some footage of people using it after the tutorial, and it looks like it works pretty good. I'm just glad they didn't try it on me, because they'd be in store for a little shock prank of their own. And that shock would come in the form of a live 240V wire being jammed up their ass. I swear, I'm such a prankster.

Thanks to Chris, who is stunning himself and who I would not actually do that to, for the tip
