Shock and Awe: the Marly experiment


BBC Four is currently repeating Jim Al-Khalili's documentary,  "Shock and Awe: the Story of Electricity",  which was first broadcast in 2011.  The first episode is devoted to 18th-century discoveries.   Catch it if you can, before it disappears from i-player as it is a brilliant programme - the camera work is stunning throughout.  There is no gimmicky docudrama, just Jim recreating the original experiments in a load of unusual locations: Charterhouse and the Royal Society in London, Leiden and the University of Bologna.

One of the most satisfying of the early experiments in electricity took place in France at Marly-la-Ville.  How could it be proved that lightning, most awe-inspiring of God's wonders, was really an electrical phenomenon?  Easy....
