The Science of Fireworks - with Chris Bishop

Professor Chris Bishop, presenter of the 2008 Royal Institution Christmas Lectures, gives a family lecture on the history of the modern firework. Through demonstrations of pyrotechnic chemistry hear how Chinese incendiaries made from honey led to the development of gunpowder; discover how the loud bangs of fireworks are routed in the origins of photography; and find out how an accident in a nineteenth-century kitchen sparked a new chemistry for firework making. Recorded at the University of Cambridge on the 4 November 2011.
