    So I didn't know what this was, had a suspicion, but I had to look it up. The second reference gives a huge clue as to what is going on in this video.
    I do a lot of work with Neodymium magnets. If you look carefully at the Mobius strip you will see that it is covered in Nickel plated tiles sandwiched to a steel core. Neodymium magnets! The little whizzing snowball is a piece of some kind of superconducting solid material. The magnetic field from the magnets is part of the reason why it is propelling the superconductor around the strip.
