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.
