Andy takes a closer look at one of his favourite demos from the 2012 Christmas Lectures, bringing together a levitating superconductor and a bewildering Möbius strip made from over 2,000 magnets. We'd love it if you helped us translate this video: http://www.youtube.com/time...
As his super-conducting boat whizzes along the track, Andy demonstrates the remarkable properties of the superconducting material (Yttrium barium copper oxide) which allows it to seemingly float both above and below the track.
With a beautiful, explosive experiment, Andy demonstrates how Humphry Davy's simple invention saved hundreds of lives from firedamp. Subscribe for regular science videos: http://bit.ly/RiSubscRibe ...
This Halloween, we thought we’d investigate the interface between pumpkins and thermite. The results were explosive. Subscribe for regular science videos: http://bit.ly/RiSubscRibe

Following his previous demonstration of levitating superconductors, Andy returns to the Ri Prep Room to investigate a question: how much does a falling magnet weigh?
The Ri's Andrew Marmery takes a break from Christmas Lecture rehearsals to describe how he designed a built a life-size Ames room for the show. The distorted room was named after ophthalmologist Ad...

When the study of crystallography first began over a century ago, it would take scientists a year to read simple molecular structures. Technology advancements and corroborated methods have since sh...
As the field of crystallography celebrates its centenary year we look back at how it all began -- with a father and son team and a humble salt crystal.
X-Ray Crystallography might seem like an obscure, even unheard of field of research; however structural analysis has played a part in almost every major scientific field since its discovery 100 yea...
In the second of his Tales from the Prep Room, Ri Demo Technician Andrew Marmery uses wire and a laser pen to recreate the famous cross-shaped diffraction patterns observed by Rosalind Franklin in ...
Sir Roger Penrose provides a unique insight into the "forbidden symmetry" of his famous penrose tiles and the use of non-repeating patterns in design and architecture.
Sir Roger Penrose demonstrates the extraordinary moiré patterns produced by overlaying and rotating two identical, repeating patterns. As the two patterns overlapped and rotated they interfere with...
