The Tenth Watch: The 95-Year-Long (And Counting) Pitch Drop Experiment

In 1927, Thomas Parnell, University of Queensland physics professor wanted to demonstrate the fluidity and high viscosity of pitch, and so created an experiment by putting a pitch sample in a glass funnel and waited for it to drip out. The first drop took eight years to fall. The ninth drop fell in 2014, and right now, the School of Mathematics and Physics of UQ has set up a live video stream, called The Tenth Watch, to await the momentous tenth drop.

Currently, the experiment has had three custodians, Professor Parnell being the first, his colleague Professor John Mainstone, was the second, and now, the third is Professor Andrew White. Read more on the Pitch Drop experiment from UQ. -via Cracked
