We've all seen pictures and videos of magnets suspended in mid air over some superconducting material bathed in liquid nitrogen. That in itself is pretty neat. But the video below goes beyond that, showing something called quantum levitation, where the superconducting material is held in place over magnets in such a way that it keeps its orientation above them. The superconducting 'puck' keeps the same height or tilt or other orientation due to quantumtatively locked levitation, even if it's moving.
Neat stuff indeed!
