What better way to get your kids to brush twice daily than by pumping two minutes of Raffi through their bicuspids? Hasbro's "Tooth Tunes" just does that. At the push of a button, the brush starts to play back the recording stored in it through a built-in transducer. The sound flows from the front teeth to the jawbone and then to the inner ear. Hasbro's talking to various artists about getting rights to their recordings. Test models with Nine Inch Nails' Closer did not make it to market.
