Trinity College experiment succeeds after 69 years - RT� News: After decades of waiting, physicists at Trinity College have for the first time captured a rare scientific event on camera.
70 years after the experiment was set up, the scientists have videoed pitch dripping from a funnel.
The experiment was begun by a colleague of Nobel Prize winner Ernest Walton in the physics department of Trinity in 1944.
Its aim was to prove that the black carbonic substance pitch is a viscous or flowing material.
