How a single-sided track allows a superconductor to float in two directions

Levitating Superconductor on a Möbius strip · 7:30 · Video: The Royal Institution · Watch at the source

In short: Watch as a superconducting boat glides along a track made of 2,000 magnets. This demonstration uses a Möbius strip to show how specific materials can defy gravity by floating both above and below the track.

This demonstration features a boat made of Yttrium barium copper oxide, a material with remarkable superconducting properties. By placing this material on a track shaped into a Möbius strip—a surface with only one side—the superconductor can whiz along while seemingly floating both above and below the track's path.
