Short Documentary by Nic Young

Engineer Jem Stansfield investigates how the crash test dummy has become an icon for safety. For 65 years he has been crashed, smashed and impaled, evolving from a simple military mannequin into a highly sophisticated measuring tool. Jem meets a whole range of dummies from the past, present and future at crash laboratories in Sweden, the UK and US to discover how their evolution has mirrored car safety improvements. An affectionate look at a unique feat of engineering which makes you laugh, gasp and wince all at once.

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. Ground-breaking high speed photography makes for some startling revelations at every step of the way.
