Of all the things people do, someone actually found the time to build this weird robotic hand that can actually “play” the piano, or just a few keys to be exact. The mechanical hand is capable of playing pre-recorded music from its speakers, moving its fingers along with the tune. At the end of the act, the hand couldn’t care less if there’s no applause; it has pre-recorded fake applause to go along as well. That’s one self-sufficient musician. The hand costs $13 and requires two AA batteries to function.
