You may have seen superconductor levitation before, but have you ever seen anything like this? … In a riveting demonstration, Boaz Almog shows how a phenomenon known as quantum locking allows a super-thin 3-inch disk to lock something in thin air…

[Here’s his TED talk on subject.](http://www.ted.com/talks/boaz_almog_levitates_a_superconductor?language=en) Even something 70,000 times its own weight can be levitated by this super-thin 3-inch superconductor disk to float over a magnetic rail — completely frictionlessly and with zero energy loss.

Experiment: Prof. Guy Deutscher, Mishael Azoulay, Boaz Almog, of the High Tc Superconductivity Group, School of Physics and Astronomy, Tel Aviv University.
