“Joey the Intern” at TechTV recently realized something interesting: When a disposable camera charges its flash, it uses a capacitor capable of generating 6,000 volts of electricity. So he ripped it open, attached a few electrodes, and voila — a do-it-yourself stun gun.

This is what my arm looked like the morning after I was shocked by our clever device. The two little red marks in the circle are burns I got. Being on the receiving end of that glove was not a day at the park.

(Thanks to Boing Boing for this one!)
