This is a real laboratory physics demonstration showcasing quantum locking (also called flux pinning). When a Type II superconductor is frozen using liquid nitrogen, it locks into a fixed position in three- dimensional space-allowing it to glide along a magnetic track or hover upside down without falling off.
