It’s literally slower than watching Australia drift north’: the laboratory experiment that will outlive us all
For more than 90 years, a funnel of pitch in Brisbane has been slowly dripping into a beaker. Nine drops have fallen, now the long wait for the tenth is on.
The pitch drop experiment was first set up by Mainstone's predecessor Thomas Parnell in 1927. Parnell heated and liquefied some pitch, poured it into a sealed funnel, and set it over the beaker inside a large bell jar. In 1930, he cut the stem of the funnel – and waited.
Nearly a century later, the original experiment - which has become the longest running laboratory experiment in the world – stands in the foyer of the physics building in the Great Court. The jar is set inside a protective plastic cube, with an analogue Casio desk clock observing each moment as students and staff wander past. The funnel is held aloft by a brass tripod; at the bottom, a shiny black balloon of pitch hovers above the empty beaker.
On a Friday afternoon in April 1979, John Mainstone, a physics professor at the University of Queensland, rang his wife at home. He wouldn’t be back that evening, he told her. For the previous 18 years, Mainstone had looked after the pitch drop experiment, a long-form demonstration of the extreme viscosity of pitch. For the first time since August 1970, the pitch was about to drip from its funnel, and Mainstone didn’t want to miss it.
Recognised by the Guiness Book of Records as the longest running scientific experiment in the world. The first Professor of Physics at the University of Queensland, Professor Thomas Parnell, began the experiment in 1927. In the more than 80 years that the pitch has been dripping no-one has ever seen the drop fall. There is now a live video feed accessible via the website. The third custodian of the Pitch Drop Experiment is Prof. Andrew White. Brisbane. Australia.
