How does the robot butterfly in a jar work?

I recently bought a robot butterfly in a jar and it's battery-powered, but what causes the little sucker to jump around?


I surfed the web and didn't get anywhere, not that i delved too deeply into the matter. Just wondering if anyone knows off-hand.|||I think it operates on a very fine string attached from the top of the jar to the butterfly causing it to jump around. So the motor in the lid of the jar moves the string and causes the butterfly to move. It really is a great invention and looks so real!
