Boaz Almog “Levitates” A Superconductor

How can a super-thin 3-inch disk levitate something 70,000 times its own weight? In a riveting demonstration, Boaz Almog shows how a phenomenon known as quantum locking allows a superconductor disk to float over a magnetic rail -- completely frictionlessly and with zero energy loss. Boaz Almog uses quantum physics to levitate and trap objects in midair. Call it "quantum levitation.
