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]
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 1980s that the pitch in the experiment has a viscosity approximately 100 billion (10 11) times that of water. [5] The eighth drop fell on 28 November ...

A former NASA engineer designed a complicated way to lift an egg into space and drop it back to Earth, recreating a popular childhood school project.
I was just watching the video stream, and comparing it with the picture in the article that is from 2007, I saw that it looks quite like the 9th drop might have ...
