Can you also explain why the balls come out very clean and well polished?Watch the stripes in both of them home made ball polishers, they spin in a perfect circle, look for the strip spinning with the strip, if it don't change its rotation its because the centrifical force of the spin is keeping all the balls spinning on the same axis, which means the balls are not rotating for a 100% buffing shin, but rather polishing the balls like a yoyo. You don't have to believe me, but if you clearly see one strip not rotating while it's spinning, then none of them are rotating while they're spinning.
