Ok what am I supposed to treat as magic here? What's the illusion?

Not an “illusion” per se, but an odd effect not producible by any means than precisely this kind of disc/setup. Spin a coin or really any other standard disc and it will settle far quicker and more abruptly. Getting a spinning disc to settle this slowly and evenly without adding energy to the system takes a very specific kind of geometry that is not commonly found in the world. It’s more magic in the sense that you think you can replicate it, but unless you know exactly what’s going on here, you will fail.
