The pitch drop experiment is one of the longest-running laboratory experiments in history, designed to demonstrate the extremely high viscosity of pitch, a substance that appears solid but is actually a very slow-flowing liquid. First set up in 1927 by physicist Thomas Parnell at the University of Queensland, the experiment involves a funnel filled with pitch that gradually forms and releases drops over the course of many years, with each drop taking roughly a decade to fall. The setup highlights how everyday intuition about solids and liquids can be misleading, revealing that some materials flow so slowly that their motion is imperceptible without long-term observation. It continues to run today, serving as a striking reminder of both the strange behavior of materials and the patience sometimes required in scientific inquiry.

That's what Joshua Graham was covered in
I don’t know about modern glass, but old glass used to do this. It would run very slowly that’s why some pains are thicker at the bottom.
This is at Queensland University, Australia.
It is simply

We use in daily use in INDIA 😎
its at my uni out side a lecture theatre
I didn't look at the years passing and thought hmmm not that slow
So is glass a liquid?
What will they do with it after it's all done?
So its ‘ pitch black’ was real.😮
She's cute
