This is a preview clip from the documentary 'Explosions: How We Shook The World' which will be shown at 8pm on 13th October on BBC Four. Jem Stansfield visits the Defence Academy of the UK in order to make the dangerous high explosive nitroglycerine. Filmed in extreme slo-mo for the first time ever for 'Explosions: How we Shook the World', just a hit with a hammer is enough to cause this sensitive high explosive to detonate - creating a supersonic shockwave and a flash of light that is almost too fast to film, even with the latest specialist cameras.
