To be or not to be...a solid

Did you know that glass is a liquid?
Not was a liquid, like molten metal before it's steel, but is a liquid, like water!
I didn't. But I do now!
I knew glass could be heated and melted and blown and twisted into strange shapes. But I didn't realize that glass remains viscous even after it cools! In other words, at room temperature, your expensive Steuben glass centerpiece is melting, albeit at a tremendously slow rate, into a puddle.
Furthermore, the fact that glass is a liquid explains why it is clear - like water. Its molecular structure is not the regular crystalline latticework of a solid. It's random and loosely spaced - like water. That's why light passes through it without being reflected or absorbed.
Just remember: Glass may be a liquid, but I don't recommend washing your face with it.
