Superconducting magnets are freakin' awesome. You should know this already. But the folks at the Royal Institution took it a step further with their futuristic upside-down, Möbius strip track that's fit for a racing game set in 21xx. Hopefully this is what the Hot Wheels of the future are like. Err, "Hot Superconducting Magnets," I guess.

But on top of the sheer cool-factor of seeing something hover upside down, you'll also get a nice explanation on how this kind of stuff actually works. It's not as great as getting an actual superconducting magnet car and accompanying track of your own, but here's to hoping. [Boing Boing]
