Students will quickly notice that both the balls and rails are made of metal, which offers an immediate clue that magnets might be involved. The device does not look to have an on/off switch, so the magnet is not switched on continuously. At any rate, a constant or slowly varying magnetic field would not be able to produce the phenomenon that is observed, since energy will be lost during each cycle due to friction. Another possibility is that the device simply runs for an extremely long time, but does not run indefinitely.
With the exception of cases involving perpetual motion, a model is not ordinarily required by the Office to demonstrate the operability of a device.
The signature of a perpetual motion machine of the second kind is that there is only one heat reservoir involved, which is being spontaneously cooled without involving a transfer of heat to a cooler reservoir. This conversion of heat into useful work, without any side effect, is impossible, according to the second law of thermodynamics.
"I have been collecting unusual things for a long time and this perpetual motion machine is one of my instant favourites. Great quality, the hidden on/off switch adds to the illusion.

The circuit takes the light from the solar cell, stores it and releases it in a pulse, making the gear wheel move, which eventually drops the marble down the spiral.
So, for example, the thought experiment of a Brownian ratchet as a perpetual motion machine was first discussed by Gabriel Lippmann in 1900 but it was not until 1912 that Marian Smoluchowski gave an adequate explanation for why it cannot work.[26] However, during that twelve-year period scientists did not believe that the machine was possible. They were merely unaware of the exact mechanism by which it would inevitably fail.
The history of perpetual motion machines dates back to the Middle Ages.[13] For millennia, it was not clear whether perpetual motion devices were possible or not, until the development of modern theories of thermodynamics showed that they were impossible.
