Our first inclination when we saw this video was that its creators used digital animation. We've encountered several similar seemingly "impossible" videos featuring colored ball sorters and musical marbles that used computer-generated technology. The latest video supposedly depicting the "perpetual" marble machine, however, was authentic footage and featured a physical product.

"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.
Probably the easiest way to do this is to use video analysis software. A video of a trajectory can be recorded with a mobile phone to be uploaded to video analysis software and analyzed frame by frame. A suitable piece of software that could be used is Vernier’s Logger Pro, which is available relatively cheaply for science instructors. Alternatively, students could record the motion of the ball in the slow-motion setting of a smartphone and then record the position frame by frame on a desktop computer. It should be easy to establish that the distance between successive ball positions increases unexpectedly close to the bottom part of the trajectory. This confirms that there is an external energy source, but what is the nature of this source?

A perpetual motion machine of the second kind is a machine that spontaneously converts thermal energy into mechanical work. When the thermal energy is equivalent to the work done, this does not violate the law of conservation of energy. However, it does violate the more subtle second law of thermodynamics in a cyclic process (see also entropy).
A more thorough analysis showed that when a physical ratchet was considered at this molecular scale, Brownian motion would also affect the ratchet and cause it to randomly fail resulting in no more info net gain. Thus, the device would not violate the laws of thermodynamics.
