Pepper spray ring and mobile phone stun gun

Pepper Spray RingAfter reading about Safety Technology's combination voice-changer/background-noise gadget that connects to your phone (reviewed in Wired's must-read Gadget Lab newsletter), I looked at some of the other things that Safety Technology sells. The Stunner, a pepper spray ring, looks like a great way to accidentally blast yourself or your friend in the face with a searing dose of capsaicin (the chemical that makes peppers hot). They also sell a stun gun designed to look like a cell phone (not the false-rumor Nokia stun gun that made the blog rounds a couple of weeks ago).
