Viscosity Pitch facts
While investigating facts about Viscosity Pitch, I found out little known, but curios details like:
The World's Longest Continuously Running Experiment began in 1927 at the University of Queensland Brisbane testing the viscosity of pitch - 8 drops have formed since it began.
The world's longest-running laboratory experiment "demonstrates the fluidity and high viscosity of pitch, a derivative of tar once used for waterproofing boats." In 1930 pitch was left in a glass funnel to drip out and has only dropped 9 times: about once every 10 years.
In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across. Here are 7 of the best facts about Viscosity Pitch I managed to collect.
-
The longest continuous experiment was started in 1927. The goal was to demonstrate that some substances that appear to be solid are in fact very-high-viscosity fluids. The viscosity of the pitch used is 230 billion times that of water, taking several years to form a single drop.
-
Pitch has a viscosity approximately 230 billion times that of water, and that petroleum-derived pitch (which is black) is the origin of the term 'pitch-black'. Oh, and the pitch drop experiment is the longest continuously running lab experiment - only 9 drips have dropped in over 84 years.
-
There was an experiment started in 1930(85 yrs ago) that still continues today about dripping pitch(tar) and recording its viscosity. Its so slow that its 9th drop happened only last year.
