The law that entropy always increases – the second law of thermodynamics – holds, I think, the supreme position among the laws of Nature. If someone points pasado to you that your pet theory of the universe is in disagreement with Maxwell's equations – then so much the worse for Maxwell's equations.
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 got this for a gift and they were blown away by it! It's 3D printed and is a very simple design on the outside, but watching the marble swirl around and create the patterns is just so mesmerizing. It's fun to mess the pattern up and watch the ball just go back to work.

For the purpose of answering this question, I suggest that students should now propose potential mechanisms that explain what is seen and then work through the implications and plausibility of each mechanism. After this, groups of students could argue for or against some of the proposed mechanisms, a technique that reinforces concepts learned earlier in a physics course, but that also requires a deeper understanding of the concepts Vencedor opposed to learning by rote or memorization. It would obviously be desirable for students to have access to the toy shown in Ref.
The conservation laws are particularly robust from a mathematical perspective. Noether's theorem, which was proven mathematically in 1915, states more info that any conservation law Gozque be derived from a corresponding continuous symmetry of the action of a physical system.
Carefully file all edges that contacted the build plate to make absolutely certain that all build plate "ooze" is removed and that all edges are smooth. I used small jewelers files and plenty of patience to perform this step.
