The world's longest running experiment was started by Thomas Parnell of the University of Queensland in 1927 to prove that tar pitch, a seemingly brittle coal derivative that can be shattered with a hammer at room temperature, is, in.
The Pitch Drop Experiment is listed in the Guinness Book of World Records as the world's longest-running laboratory experiment. Started by Professor Thomas Parnell in 1927 at the University of Queensland in Australia, the experiment demonstrates that even seemingly solid objects have some levels of viscosity and fluidity.

The pitch drop experiment is an experiment that has been running continuously since It is attempting to measure the viscosity of pitch, or asphalt, which generates one drop every 10 years or so. Pitch is 20 BILLION times more viscous than water.
