Many students of all ages enjoy the use of music while doing homework and the Shake Shake Radio Pen is a great way to promote studying.
Shake Shake is a kinetic pen that has a built-in radio. The radio, however, does not work unless the pen is being used (or shaken). The radio portion uses the kinetic energy from the use of the pen to play music.
This pen is ideal for high school and college students, who tend to get distracted during their studies.
