“Fake!” I hear you cry. That’s what I thought, especially as the above video has comments disabled, however, the next video goes some way to explaining how this could be possible.
To understand how this works, take a read of the Meissner effect and diamagnetic (ism) over on Wikipedia. Essentially, when you cool something to very low temperatures (that’s what the liquid nitrogen is for) certain materials transition to a superconducting state and that’s when it creates an equally opposing magnetic field (which makes it hover).
I still think there’s a bit of CGI going on there though. If not, I want one for Christmas. Ok?
