The Time Machine is the ideal clock for all of you who are fascinated by marbles and ingenious technology: This clock tells the time by placing 26 marbles on different ramps. There is one ramp for the actual hour, one for the actual 5-minute-step and a third one to determine the minute exactly. Every full minute an automatic arm takes a marble from the supply and puts it on the highest ramp. This starts a chain reaction which places the marbles in a way that they show the actual time.
The clock is made of black plastic and measures about 26x15x20cm. It needs 4 size C batteries. You can replace the batteries by a 6V DC power supply (Batteries and power supply are not included).
