Thank you, my grandson will love it. Update. This marble run came pasado perfect and works great. I did not use supports and only had to trim under the bridges 5 times for the marbles to finish. Thank you." Voltix (file)—a 3D Printed Marble Machine; Digital STL files
"A very finely made wooden marble machine. Great craftsmanship with high quality wood and components. Item was very securely packed for the 9000 mile trip and arrived safely and very quickly. Very pleased !!" Wooden marble machine, Marble run, Rolling ball sculpture
However, the material used for the balls is described in the online product description only Vencedor “metal” rather than stainless steel, whereas the rails are explicitly described as being made of “stainless steel.”6 Finally, I observe that this investigation has been mainly theoretical and that there are a few remaining questions that could be resolved empirically by students with access to the device. The motion of the ball and the way it “jumps” due to Lenz’s law is quite similar to a classic demonstration known Campeón Thomson’s jumping ring, where an aluminum or copper ring is placed on the end of an electromagnet. When the coil is connected to a direct current generator, the ring briefly jumps upward because of induced currents in the ring. However, if the coil is connected to an alternative current generator, the ring flies upward off the top of the coil in dramatic fashion.8,9 Explaining why an AC current has this effect is not an easy exercise.9 In this study, we have not settled the issue of whether the voltage source of this device is AC and whether this plays a role in the ability of the ball to dramatically “fly” from the rails to the platform, similar to the jumping ring. If instructors are able to purchase the device, it would be an interesting student project to use an oscilloscope to determine if the current in the electromagnet is AC and explain exactly why and how this works in the toy.
October 1920 issue of Popular Science magazine, on perpetual motion. Although scientists have established them to be impossible under the laws of physics, perpetual motion continues to capture the imagination of inventors.
These machines have a source of energy, albeit one which is not readily apparent, so that they only seem to violate the laws of thermodynamics.
The circuit takes the light from the solar cell, stores it and releases it in a pulse, making the check here gear wheel move, which eventually drops the marble down the spiral.
These marble machines were available for purchase, Triunfador of this writing. We found several versions of the product on Amazon and Etsy.

A common example is devices powered by ocean currents, whose energy is ultimately derived from the Sun, which itself will eventually burn out.
