At the University of Queensland, there is a display containing the longest-running laboratory experiment in the world. It's been going for so long that two of its custodians have died before seeing ...

At Trinity College Dublin, a science experiment started 69 years ago has finally yielded results, after pitch was observed dripping for the first time ever, and proven to be a viscous fluid. Tar pitch ...

The pitch has dropped – again. This time, the glimpse of a falling blob of tar, also called pitch, represents the first result for the world’s longest-running experiment. Sadly however, the glimpse ...

In 1944, a colleague of Ernest Walton, the first person in history to successfully smash an atom, began an experiment of a decidedly larger and lengthier variety. In a physics lab at Trinity College, ...

In 1927, a researcher at the University of Queensland in Australia began what’s widely recognized as the longest-running experiment ever, the so-called “pitch drop.” It’s a simple set up: fill a flask ...
