Glass is a super-cooled liquid and flows even more slowly than pitch.

Wrong!

it might be a super cooled liquid but it does not flow.

From Wikipedia:

The observation that old windows are sometimes found to be thicker at the bottom than at the top is often offered as supporting evidence for the view that glass flows over a timescale of centuries. The assumption being that the glass was once uniform, but has flowed to its new shape, which is a property of liquid.[41] However, this assumption is incorrect; once solidified, glass does not flow anymore. The reason for the observation is that in the past, when panes of glass were commonly made by glassblowers, the technique used was to spin molten glass so as to create a round, mostly flat and even plate (the crown glass process, described above). This plate was then cut to fit a window. The pieces were not, however, absolutely flat; the edges of the disk became a different thickness as the glass spun. When installed in a window frame, the glass would be placed with the thicker side down both for the sake of stability and to prevent water accumulating in the lead cames at the bottom of the window.[42] Occasionally such glass has been found thinner side down or thicker on either side of the window's edge, the result of carelessness during installation.[43]

5. Listen to John Major give an interview
6. Watch an episode of WailEastenders
7. Watch the Jonathan Ross show
8. Drive a Nissan Sunny.
9. Eat Mayonaise
10. Watch pitch drip through a funnel.

From Wikipedia:
Also from the same article

Laboratory measurements of room temperature glass flow do show a motion consistent with a material viscosity on the order of 1017–1018 Pa s.[39]

So it does flow, but so slowly that it may as well not

I've been keeping an occasional eye on this after hearing it mentioned on a podcast (possibly Radiolab).

I think the original scientist was once within five minutes of seeing it drop, but had popped out to make a brew.

Aso from the same article which precede the words that you quote:

The notion that glass flows to an appreciable extent over extended periods of time is not supported by empirical research or theoretical analysis

Aso from the same article which precede the words that you quote:

From the Scientific American a publication I trust a bit more than Wikipedia "Like liquids, these disorganized solids can flow, albeit very slowly. A mathematical model shows it would take longer than the universe has existed for room temperature cathedral glass to rearrange itself to appear melted."

Find something incredibly boring, then argue about it! That's the life!

hmmmm suppose... but i tuned out after the, for me, heyday of the 80's

I watched seriously up until about 10 years ago, and now, most of the people I barely know, but I did see a guy the other day who made me want to watch, a Thai guy called Dechawat Poonjaeng (spelling). He might have been knocked out, but boy he was entertaining!

They might say he's eccentric, and yes, he was a bit odd at times, but it just seemed to me that, since it was his Crucible debut..... at the age of 34 (he only turned pro a couple of years ago), he was taking it easy and enjoying himself instead of being deadly serious (and dull) like everyone else. He was happy just to be there and I hope to see him again in the future!
