The viscosity of a fluid refers to how easily it moves under stress. A highly viscous fluid will move less readily than a fluid of low viscosity. The term fluid refers to liquids and gases both of which have viscosity. The accurate prediction and measurement of the behavior of a fluid in motion is essential in the design of efficient industrial plants and apparatus.| Sciencing
Before the 20th century, people did not know that the continents moved around the planet. Continental drift is such a slow process that you can't see land masses shift with the naked eye. Because the continents never stop moving, however, the world map you know today will not look the same in the distant future.| Sciencing
The Pitch Drop Experiment has been running since 1927 at the University of Queensland, Australia. It consists of black pitch contained in a glass funnel, with the entire apparatus enclosed in a container. It demonstrates that pitch is actually an extremely viscous liquid. Once the stem of the funnel was cut, the pitch slowly began to drip. In late 2000, the 8th drop fell. From this experiment it has been possible to demonstrate that the viscosity of pitch is about 100 billion times that of wa...| Guinness World Records
