World’s slowest-moving drop caught on camera at last
How long would you be willing to wait for a drop of the black stuff in Dublin? After 69 years, one of the longest-running laboratory investigations in the world has finally captured the fall of a drop of tar pitch on camera for the first time. A similar, better-known and older experiment in Australia missed filming its latest drop in 2000 because the camera was offline at the time.
The Dublin pitch-drop experiment was set up in 1944 at Trinity College Dublin to demonstrate the high viscosity or low fluidity of pitch — also known as bitumen or asphalt — a material that appears to be solid at room temperature, but is in fact flowing, albeit extremely slowly.
^^ The oldest known pitch drop experiment began at Cambridge University in Australia in 1927 by Professor Thomas Parnell. The first drop fell a decade later. Professor John Mainstone, pictured, has been custodian of the Australian test since the 1960s but has missed every drop
