A pitch drop experiment was begun at the University of St Andrews in 1927, the same year as the Queensland experiment. No evidence has emerged of any contact between Parnell and the instigator or instigators of the St. Andrews experiment. The pitch in the St. Andrews experiment flows in a largely steady, but extremely slow, stream. [20]
The pitch drop experiment is a famous fluid breakup experiment using high viscous tar pitch. The rate of breakup is slowed to such a degree that only 11 drops have fallen since 1927. The rate of breakup is slowed to such a degree that only 11 drops have fallen since 1927.
In 1927 Parnell initiated an intriguing experiment to allow long-term observation of the behaviour of material known to have an extremely high coefficient of viscosity. Thus began his now famous pitch drop experiment, which, against all the odds, has been carefully preserved by UQ Physics to this day. [6] [7] [8]
Physics – Presented jointly to John Mainstone and Thomas Parnell of the University of Queensland, Australia, for patiently conducting the so-called pitch drop experiment that began in the year 1927—in which a glob of congealed black tar pitch has been slowly dripping through a funnel, at a rate of approximately one drop every nine years.

The pitch drop experiment taking place at University of Queensland is a long-term experiment which demonstrates the flow of a piece of pitch over many years. For the experiment, pitch was put in a glass funnel and allowed to slowly drip out. Since the pitch was allowed to start dripping in 1930, only nine drops have fallen. It was calculated in ...

The University of Queensland pitch drop experiment has been ongoing since 1927. A long-term experiment is an experimental procedure that runs through a long period of time, in order to test a hypothesis or observe a phenomenon that takes place at an extremely slow rate.
The live view is still available (as seen below), from the experiment’s temporary location. ... Is this Wikipedia article about the pitch drop at the University of ...
