If you haven't seen Blue Man live, this is the next best thing. Wave the percussion sticks over the eight motion-sensitive tubes and they'll mix in the troupe's signature tubes and drums, as well as steel drums, the xylophone and the marimba. Plug in an iPod or MP3 player and kids can play along to their favorite hits. And if you have seen Blue Man Group live, don't worry - no smocks are required. Age five and up.
