Video: Supercooled Quantum Levitating Hoverboard Lets Students Glide on Air
You probably saw that super viral quantum locking levitation video that bounced all over the Web last week (though technically it's been around since summer) in which a team of researchers plays with some liquid nitrogen, a small superconducting disc, and some strange quantum phenomenon that makes the disc hover above a magnet, no strings attached. This week's levitation vid taps a similar phenomenon known as the Meisnner effect to achieve this kind of levitation at a decidedly cooler scale: that of the hoverboard. MagSurf, build by researchers at Universite Paris Diderot in France, flips the strange world of the quantum into a more sci-fi application, essentially turning a skateboard like platform into one big magnetic superconductor. Using liquid nitrogen, the team turn the platform super-cold, creating an electromagnetic field that is expelled from the inside of the board. It's not quantum locking--the skateboard is too big to mimic that...
