I made this film in the first half of the year and it features one of my favourite demos from the 2012 Christmas Lectures - a levitating superconductor flying around a Möbius strip made from over 2,000 magnets. The thing is an absolute joy to watch and perfectly shows off the superconductor which can be seen hovering above and below the track! The video went on to be one of our most successful pieces - getting over half a million views soon after it was released - it got picked up on a number of popular blogs and websites, from Gizmodo to Boing, Boing!
It took ages to edit mostly because I was getting all caught up with the detail of explanations and how best to condense everything down into as concise a package as possible - I ended up shelving it for several months and nearly didn't return to it - I'm so glad I did! It really helped coming back to it with a fresh mind and I soon worked round my problems to get it out of the edit.
It was shot all on a single camera which I think also benefited the explanations - we had to repeat these a number of times to obtain variation in shots so we were able to refine these with each subsequent take. Unusually for this series of films I used our 70-200mm lens which gave really nice close-ups, both on the hovering boat/train but also of Andy - these cut in really nicely to give some variation in shots during the longer explanation sections.
