Quantum levitating

A video created by researchers at Tel Aviv University in Israel has the Internet buzzing. Though rather simple, it just looks really cool, hence all the attention. It’s a demonstration of quantum locking, though to non-science buffs, it looks more like science fiction come to life. In the video a disc, obviously frozen due to the vapor rising from its surface hovers over a surface.

This is nothing new of course, everyone’s seen it in science class. What is new is that when the demonstrator turns the disc, it stays hovered at that angle. This is in contrast to the wobbling we’re used to in such demonstrations. Next, the disc is set over a different surface where it is made to spin. But that’s only the beginning. The disc is then set on a track where it zips around in midair. And again, it can be made to do so at whatever angle is desired. Then, the track is turned upside down and the disc hovers below it, again zipping around.
