The Newton’s Clock lies flat on a table, in a lobby or a mall, and the balls’ speed and direction are controlled with electromagnets. Tracks also spiral in and out between the circular tracks to cause for example a 60 minute ball to become a 5 hour ball and the old hour ball to travel to the ring for seconds.

At 60 rpm, the primary clock movement is a ball speeding around the outer track, counting off the seconds with a “tick, tick, tick” as each one hits and exchanges energy with its companion to then take up a new position on the clock face. At intervals, a ball is steered inward to the minute ring to modify its position. The old minute ball returns to the outer ring unless it’s also time to alter the hour ball on the innermost ring.

It should be fascinating to watch the balls’ circular sprint and the rapid appearance of new stationary balls in the opposite direction. At each new hour, all the balls would sequentially strike each other, swerving through circular and spiral tracks, in less than a second.
