Video: Levitating Superconductor on a Möbius strip

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.

Christmas Lectures 2012 – Behind the Scenes

The Modern Alchemist

One of the great pleasures of working at the Royal Institution is witnessing the frenzy that goes on behind the scenes in the lead up to the Christmas Lectures. This year the lectures cover the chemical elements and are presented by Dr Peter Wothers, a fellow of the Royal Society of Chemistry and teaching fellow at the University of Cambridge.

The lectures themselves are available for a limited period on iPlayer, but will also be available to stream indefinitely on the Ri Channel, the team behind them have done an incredible job and so they’re well worth a watch – you don’t necessarily need any scientific background or knowledge of Chemistry to enjoy them!

Naturally this year’s subject lends itself well to the presentation of scientific demonstrations and there has been plenty of opportunity for loud bangs and fire spewing explosions. However, the lectures have also provided chance to perform some very rare and unusual demonstrations – and it’s these that have formed the subject of a couple of behind the scenes films produced for the Ri Channel:

Reacting Caesium and Fluorine (First time on camera)

Fluorine and Caesium are the two most reactive elements in the periodic table and so for the lectures, Peter was very interested in trying to react them both together. However their extreme reactivity also means that they’re both very dangerous to work wit, so it was important Peter found the right person to work with! Enter Dr Eric Hope a Fluorine specialist at the University of Leicester and so on a grey day in November we travelled up to see how this reaction might work and I think it might be the first time it has ever been caught on camera!

What was particularly nice about this meeting was that Peter had never previously seen Fluorine and Eric had never seen Caesium! This demo features in the second lecture, ‘Water: The Fountain of Youth’.

Cloud Chamber

I was so pleased I got to see this demo with my own eyes, I’d previously heard a lot about cloud chambers and seen a few bits of ropey footage on the internet, but never actually seen one in the flesh (so to speak). It’s essentially a particle detector with a sealed environment that is supersaturated with alcohol vapour and as charged particles zip through the vapour they ionize it, allowing condensation trails to form.

It’s an absolutely beautiful thing to look at, as it makes visible the background radiation that exists all around us and on the last day of recording I was lucky enough to capture this close-up on camera:

This demonstration features in the third lecture entitled ‘The Philosopher’s Stone’.

Testing Hydrogen Balloons

Lastly, the Christmas Lectures wouldn’t be complete without some sort of gratuitous explosion and so here’s a little film about testing different sized hydrogen balloons:

24 Films for Advent…

…or how to kill yourself slowly before Christmas.

Advent Tilt

With the 2012 Royal Insitution Christmas Lectures exploring the chemistry of the modern world, we wanted to produce a suitable project to promote the lectures online.

So for the last two months I have been working frantically to create 24 short films, each asking a bunch of well known scientists, science communicators and famous faces what their favourite element is – the films are being released daily and are housed within a beautiful interactive advent calendar built by Archive Studios. View the advent calendar here.

Trailer for the series:

It’s a bit of a silly question so the films are all a bit tongue in cheek to a certain extent, but there’s a nice variety across them – from simple pieces to camera, to more involved short films centered on specific elements. The films also include a lovely animated ident produced by the friendly folks over at 12foot6.

The idea for the series came from a question posed to interview candidates for the Christmas Lectures Researcher role – who were asked what their favourite element was and why – the answers given were often surprisingly personal and often witty, it seemed like a great way to explore the elements from a very personal perspective.

We’ve worked hard to produce a nice variety across the films to avoid repeating the same format – hopefully this will encourage people to keep checking back on a daily basis! The series also includes a huge range of individuals including, amongst others: Brian Cox, Mark Miodownik, Dick & Dom, Helen Czerski, Dara O Briain, Liz Bonnin, Andrea Sella, Jerry Hall and this year’s Christmas Lecturer, Dr Peter Wothers. We hope there are a few surprising faces amongst the line up.

My favourite films of the series so far are…

Andrea Sella in the glassblowing workshop:

Helen Arney’s Boron Song:

Jerry Hall talking about Copper:

Helen Czerski’s piece on Calcium:

Tech stuff:

The films were pretty much all shot on a Panasonic AF101 – using a range of lenses, however mostly with a Panasonic Lumix 12-35mm lens. For a couple of the films I was lucky enough to work with BBC producer Tom Hewitson, who brought with him a Cannon XF305. Sound was recorded via Sennheiser ew100 G3 wireless radio mic set and also with a Rode NTG-2 shotgun mic. Edited on FCPX and exported as 720p, h264. The films can also be viewed on YouTube and on the Ri Channel.

Hope you enjoy them!
