Physicists at Queen Mary University of London have set up a new pitch drop experiment for students to explore the difference between solid and liquids. Known as the 'world's longest experiment', the ...

86 years ago, the University of Queensland in Australia began conducting an experiment in which the flow rate of a piece of pitch was measured. For those of you who may not know what pitch is, it's a ...

A clever tweak is letting students “cheat” at one of the world’s longest running experiments. Although pitch – or bitumen – seems solid at room temperature, it flows like a liquid given enough time.

It took 69 years, but at last we’ve seen the pitch drop. One of the world’s longest-running experiments climaxed last week, when a finger-sized bulb of pitch (bitumen) separated from its parent bulk ...

Researchers at Trinity College Dublin have some long awaited test results: After 69 years, they have captured on video a drop of pitch, also known as bitumen or asphalt. The experiment proves pitch is ...
