Want to inculcate a good brushing habit in your kids, but don’t know how to? Let Hasbro help with its new Tooth Tunes toothbrush. These special bathroom devices will play a tune, where you aren’t supposed to stop brushing until the music stops. Interestingly enough, it uses bone conduction technology to get the tunes to your head via your jaw, which means you can only hear the tunes whenever you maintain the proper brushing technique. This toothbrush ain’t too green though as it uses three AAA batteries and comes with a non-replaceable head. Might as well get an alarm clock for the bathroom as your kids brush their pearly whites till the alarm rings.
