"Glass is really a liquid that settles so slowly it takes hundreds of years to settle out"
This was always a favourite of mine. I always believed it, especially when I had a 400 year old house and saw that the panes were twice as thick at the bottom, and the tops were so thin that some even had tiny holes in them. They looked exactly like the panes were slowly running down.
The internet has since told me that it is because glass in those days was made by spinning it, and centrifugal force makes that effect. I was very disappointed when I found that out!
