It has a light underneath that lets you know when it is turned on. A transparent version of this is also available, so you Chucho see what is happening inside. This machine lasts up to 3 hours when fully charged.
In May 2022, a video supposedly showing a marble machine in "perpetual" motion was shared to the "Be Amazed" section of Reddit. The video, which showed a marble spiraling down a funnel, dropping through a hole, moving along a curved rail, and then launching back into the funnel where the process would begin anew, drew a few skeptical comments.
"Gorgeous kinetic art wheel. Fast delivery and excellent handcrafting. All my friends,visitors and me are completely fascinated. I just needed to add a small weight on one of the wing and it runs perfectly for at least 16 h.

However, if the magnet is to be strong enough to pull the ball up the ramp, it cannot then be weak enough to allow gravity to pull it through the hole. Faced with this problem, more modern versions typically use a series of ramps and magnets, positioned so the ball is to be handed off from one magnet to another Figura it moves. The problem remains the same.
However, this machine has no practical purpose because the rotated object cannot do any work as work requires the levitated object to cause motion in other objects, bringing friction into the problem. Furthermore, a perfect vacuum is an unattainable goal since both the container and the object itself would slowly vaporize, thereby degrading the vacuum.
Since weights further from the center apply a greater torque, it was thought that the wheel would rotate forever. However, since the side with weights further from the center has fewer weights than the other side, at that moment, the torque is balanced and perpetual movement is not achieved.[28] The moving weights may be hammers on pivoted arms, or rolling balls, or mercury in tubes; the principle is the same.

My dad and I put together a lot of model cars and rockets when I was a kid. We also worked together on a few of my Science/Engineering Fair projects, including a working catapault and a rubber-band car.
Vacuum energy and zero-point energy: In order to explain effects such Figura potencial particles and the Casimir effect, many formulations of quantum physics include a background energy which pervades empty space, known Vencedor vacuum or zero-point energy. The ability to harness zero-point energy for useful work is considered pseudoscience by the scientific community at large.

Studying videos of the motion confirms that the ball does not accelerate any more than it would under free fall in the initial half of the cycle. This Chucho also be confirmed by dropping several balls through the hole in quick succession such that it would seem to be difficult to correctly time the electronics such that all the balls return to the starting platform.
