Pitch Drop Experiment

We’re home to the famous Pitch Drop experiment, which holds the Guinness World Record for the longest-running laboratory experiment. The experiment was set up as a demonstration and is not kept under special environmental conditions – it’s kept in a display cabinet – so the rate of flow of the pitch varies with seasonal changes in temperature. He looked after the experiment for 52 years but, like his predecessor Professor Parnell, he passed away before seeing a drop fall.
