The University of Queensland pitch drop experiment, demonstrating the viscosity of bitumen. A pitch drop experiment is a long-term experiment which measures the flow of a piece of pitch over many years. "Pitch" is the name for any of a number of highly viscous liquids which appear solid, most commonly bitumen, also known as asphalt. At room ...
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.
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.
Natural bitumen from the Dead Sea Refined bitumen The University of Queensland pitch drop experiment, demonstrating the viscosity of bitumen. Bitumen (UK: / ˈ b ɪ tʃ ʊ m ɪ n / BIH-chuum-in, US: / b ɪ ˈ tj uː m ɪ n, b aɪ-/ bih-TEW-min, by-) [1] is an immensely viscous constituent of petroleum. Depending on its exact composition it can ...

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.
At the University pavilion the world's longest lab experiment was on display. The pitch drop experiment , which features tar pitch slowly dripping through a funnel at a rate of nine drops in 81 years, actually made an unseen drop while on display.
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]
