Ball Clock Time Machine
Relax as you watch a Ball Clock Time Machine in action. You will see that every 60 seconds the arm of the clock will pick up a ball and drop it onto a grooved lane. The ball rolls down the lane and adds itself to the other balls that indicate what time it is. The sound of the clock in action is rather pleasing. You can hear a gentle ticking in the background and the comforting sound of the ball clattering and rolling down the grooved channels.
