That’s not how the real one works, the real one has a censor magnet that speeds the ball up, using perpetual motion I believe. It helps it stay silent.
Those things are a great desk ornament but for those that aren’t knowledgeable with some form of science, you can’t generate power out of thin air, disregarding the motor in the device, eventually the marble would gradually lose power to produce the momentum to continually circulate the device
this is actually the Chinese one you bought, the actual one uses an electrical magnet at the bottom to bring the ball to it then let go therefore propelling the ball up the ramp.
For those who don’t know… The first video of this so called “perpetual motion” device isn’t powered by a small motor. It is actually powered by a small magnetic force within that wooden base. Your welcome.
That’s a slightly more obvious one- the really expensive ones will use electromagnets. I don’t blame puff for not having one of those for a demonstration though, they’re really pricey for a fake perpetual motion device
