This crazy accessory is built for the iPod. It is a teeth whitening system which is called Rock My Teeth. When used for 30 minutes it promises whiter teeth. Using bone conduction you can crank up the volume of your iPod to vibrate through your teeth as the peroxide strips whiten your teeth. According to Yahoo, it does work as well as the regular strips but just adds the iPod music to the whole teeth cleaning process.
