If you have ever wanted your own set of monkey balls you are in for a treat. These magnetic monkey balls even sing when you play with them and can make different sounds depending on the nature of your play.

Spin your balls in the air and they will make a whistling noise, attach your balls to each other and swing them like a pendulum back and forth, but beware if you get your balls too close together and they might crash into each other thanks to the magnetism monkey balls possess. Trust me no one likes it when their balls crash together. Place your balls on the desk, pinch them and spin them about to be greeted by a subtle fluttering sound, try spinning your balls on different surfaces to get different sounds. Beware; don’t leave your balls lying around they can damage CRT displays and pacemakers with their magnetism. If you have always wanted your own set of Monkey Balls to play with, ThinkGeek has them in stock right now.
