What is the worlds longest running lab experiment?

Back in 1927, Australia’s University of Queensland physicist Thomas Parnell started what is now recognized by the Guinness Book of World Records as the longest running lab experiment. Dr. Parnell wanted to examine the viscosity of pitch, a tar like substance, by observing the speed at which it flows from a funnel into a jar. Since the pitch was first poured in 1927, only nine drops have fallen, with the last one occurring in April 2014.

This long running experiment has applications that remain relevant to high viscosity polymers and liquids seen in today’s applications. One such application is in 3D inks which can have viscosities greater than 50,000cP.

Lubricant Health & Viscosity

As a lubricant begins to breakdown it undergoes significant viscosity changes. These viscosity changes can play a critical role in the life and performance of moving parts. For example, knowing when to change the engine oil in a car is straightforward, every 3,000 to 5,000 miles is a good rule of thumb. Going beyond the recommended scheduled oil change runs the risk of critical component failure leading to engine damage. However, what if you don’t have a convenient method, like miles driven, to gauge the health of your lubricant? How will you know when the lubricant begins to breakdown? The solution to this is knowing your viscosity!

Ok, here’s the scene...An explorer is traipsing through the jungle, visibility is low due to the dense vegetation, he’s chopping away at the vines and plants when suddenly he enters to clearing.
