Ever heard of quantum locking? That’s the crazy demo you see above.

Curious scientist Boaz Almog is making an extremely cold superconductor (that super-thin disk) hover — dead still — above a magnet. And like a mad scientist’s version of Hot Wheels, he’s pushing it into a frictionless dash around and around a magnetic track.

See, superconductors are unique in two ways: They allow electrical currents to pass through without friction, and they hate magnetic fields. Once a material is in a state of superconductivity — which comes from being very, very cold — it tries to stay in that state.

So when you put it over a magnet, the superconductor locks in place to prevent any strands of magnetic field from moving around inside it and generating heat. And if you put it over a circular magnetic loop and give it a gentle nudge, it gets locked in a mesmerizing loop.

Pretty cool. No pun intended. Watch the full demonstration »
