The Invi security bracelet repels assailants with a viscous stink

Engadget ---------- It's a dangerous world out there but walking around armed with knives or firearms isn't always an option for many people. That's where the Invi self-defense bracelet comes in.

To activate the bracelet, the wearer first unlocks a small safety clasp, then yanks hard on the leather strap. Doing so breaks a concealed canister containing the company's proprietary stink blend. One whiff of that stuff is enough to give most muggers second thoughts -- and you enough time to make an escape or at least call for help. To learn more click on the picture below to read the article.
