Explosions: How We Shook the World

Engineer Jem Stansfield is used to creating explosions, but in this programme he uncovers the story of how we have learnt to control them and harness their power for our own means. From recreating a rather dramatic ancient Chinese alchemy accident to splitting an atom in his own home-built replica of a 1930s piece of equipment, Jem reveals how explosives work and how we have used their power throughout history. He goes underground to show how gunpowder was used in the mines of Cornwall, recreates the first test of guncotton in a quarry with dramatic results and visits a modern high explosives factory with a noble history.

Stuff: A Horizon Guide to Materials

Engineer Jem Stansfield looks back through the Horizon archives to find out how scientists have come to understand and manipulate the materials that built the modern world. Whether it is uncovering new materials or finding fresh uses for those man has known about for centuries, each breakthrough offers a tantalising glimpse of the holy grail of materials science - a substance that is cheap to produce and has the potential to change the world. Jem explores how a series of extraordinary advances has done just that - from superconductors to the silicon revolution.
