The wonders of.... water (science article)

Post by JR8 » Tue, 12 May 2015 1:06 pm

I found this article very thought provoking. It reminded me of the day I learned that glass is a not a solid, but a ('super-cooled') liquid. I.e. given time a pane of glass will become thicker at the bottom that the top. Both are very contrary to popularly perceived wisdom :)

Urban legend. Reason is, those glass panes weren't completely set when they were moved, thus allowing some of the still-liquid glass to slightly pool at the bottom.
