Forget oil, coal and gas - a new set of materials is shaping our world and they're so bizarre they may as well be alien technology. In the first BBC documentary to be filmed entirely on smartphones, materials scientist Prof Mark Miodownik reveals the super elements that underpin our high-tech world. We have become utterly dependent on them, but they are rare and they're already running out. The stuff that makes our smartphones work could be gone in a decade and our ability to feed the world depends mostly on a mineral found in just one country. Mark reveals the magical properties of these extraordinary materials and finds out what we can do to save them.

Making Sound

At the Palace of Westminster, Helen teams up with scientists from the University of Leicester to carry out state-of-the-art measurements using lasers to reveal how the most famous bell in the world - Big Ben - vibrates to create pressure waves in the air at particular frequencies. This is how Big Ben produces its distinct sound. It's the first time that these laser measurements have been done on Big Ben. At the summit of Stromboli, one of Europe's most active volcanoes, Helen and volcanologist Dr Jeffrey Johnson use a special microphone to record the extraordinary deep tone produced by the volcano as it explodes. Finally, at the University of Cambridge's Institute of Astronomy, Helen meets a scientist who has discovered evidence of sound waves in space, created by a giant black hole. These sounds are one million billion times lower than the limit of human hearing

Let It Snow!

In this extraordinary documentary we are going to witness very different kinds and situations of snowing: from howling blizzards to the gentlest and loveliest of weather events, from huge handkerchiefs quietly falling to the needle-sharp attack of hard, heavy grains. Snow - what is it really? How is it created - naturally and artificially? Thanks to CGI and new camera techniques we can actually see this process for the first time and listen to the incredible, inaudible music of snowfall, of myriads of tiny crystals touching and rolling and settling. Each snowflake is unique and bears more secrets than we could imagine. Did you know that different kinds of music influence the crystallization process and the shape of snowflakes? And have you ever imagined that we would be able to produce artificial snow that melts at 30 degrees Celsius? With this in mind: just let it snow!
