:''That {{w|glass}}, while seeming solid, is actually an extremely viscous liquid and will flow over time, as is seen on older buildings where the window panes are thicker at the bottom.''

This myth likely arises from the fact that glass is an {{w|amorphous solid}} without a well-defined freezing point. In fact, glass becomes effectively solid once it cools down to around 1400 degrees centrigrade. At room temperature, it cannot flow at perceptible rates over human timescales. Old window panes had variable thickness due to the manufacturing process, and the thick end was generally (though not always) placed at the bottom for stability.

In the title text a kid asks his grandfather what it was in the ''Before time'' - referencing to the time before people had to read through this Wikipedia list. The grandfather remembers back to those horrible days, when people would tell that glass was a ''slow-flowing liquid''. He exclaims that the young people today (in that universe) don't know how good they have it. (A direct reference to Randall's wish of living in such a time/universe.) This is atypical, since many old folks always claim they lived in the ''good old days''. But this would be such an improvement in general well being, that even the old would not remember the old days fondly. (Of course this is written by a young Randall so that would explain this misconception. The old days was always much better as we all know... Or is that just another misconception that need to be on the Wiki-list?)
