The Motion of your body can actually charge an MP3 Player

It is something new and exiting. It is hard to believe that human's body shaking can charge mp3 player's battery but it is true. Shake is a design concept that makes use of kinetic energy in order to charge the battery. A person just needs to shake his/her body for recharging the battery. Just turn on "Hold" button and start shaking and once the battery is charged, you can turn off the "Hold" button to play and pause the mp3 player. You can give life to electronic device by your physical action, unbeleiveable!!!!!
