One of the world's most fabulous experiments

Because this experiment is being conducted over such a long duration, they probably write a news article about it every decade or so.  This article brought back memories of reading about this experiment sometime in my past.   I suspect it was when the last drop fell, in the year 2000.  It's just fascinating -- watching the flow of the world's most viscous liquid.  I wonder how it started;  did they just put a block of pitch into the container and sit back and watch?  That's what it looks like they did.

Watching pitch flow, drop by drop

Actually, this site explains the experiment and how it was set up:
