Science is cool. If you don’t believe us, just click play on the video above and watch how Andy, from The Royal Institution, plays with a high-temperature superconducting magnet. Once cooled, a superconductor starts behaving in new ways, one of which includes seemingly defying gravity.

Sadly, the use of hugely powerful neodymium magnets in that race track means you won’t see the above demo available as a toy, this Christmas.

Eleven years ago Christo started writing about technology for one of South Africa's (then) leading computer magazines. His first review? A Samsung LCD monitor. Hey, it was hot news, back then. Nowadays he gets more excited about photography, cars, game consoles, and faster internet connections. He's sort of an Apple fan, but will take any opportunity to remind you about his Windows-powered home theatre PC and desire to own a vanilla Android tablet.   Currently uses: Apple 13-inch Macbook Pro with Retina Display, Apple iPhone 5, Microsoft Laser Mouse 6000, Audiofly AF78 Earphones, Xbox 360, Nikon D50.
