Watch time pass while observing the science of physical energy and the power of machines. -- A battery-operated motor lifts a steel ball bearing onto a durable concentric track at regular intervals. Here it moves with others on a slow downward course, both halted and propelled by 'see-saws' that tip when correctly weighted. Correct time can be read by observing the numerals that the balls are aligned with - hours and minutes are both indicated. -- This intriguing conversation piece is encapsulated in a clear, impact-resistant case. The base measures 10" x 6", the clock mechanism stands 8" high. -- Powered by a 6V AC adapter (not included) or via 4 "C" batteries (not included). -- Resources: -- » See It Work (Flash Movie)
