Superconducting Quantum Levitation on a Möbius Strip

There's a phenomenon involving superconducting called quantum levitation. Similar to magnetism I believe. Anyway, it allows you to hover a small disk a certain length above a superconductor. But it will always stay at that distance, even upside down. Since it's hovering, you can spin it around the superconducting track with almost no friction. Here, they made the track a Möbius strip.

It has nothing to do with quantum physics. The mist you see is probably some contained liquid nitrogen on a superconductor. (I think) It allows the "car" to stay above the track but not touch the track allowing no friction. It's called the Meisner Effect, it's really cool.
