One of life’s litting annoyances is reaching for the car’s door handle and getting a tiny but nasty shock of static electricity as your fingers come in contact with the metal. Yowch. This Static-Discharging Keychain takes care of that problem. Simply grab one end of the keychain and touch the other end to a metal object, and the built-up static electricity will discharge painlessly through the keychain. As a bonus, when the spark flies, the keychain will light up for an instant. Now that’s cool! $14.
