Since my high school days, I learned that glass is a liquid. (Science naive students thought glass is solid, and the smarty pants knew it was actually a liquid:) Yesterday, while I was telling this interesting fact to my daughter, my wife argued that glass is solid. I googled to explain them why glass is a liquid, but apparently science web sites points out that "glass is liquid" is an urban legend. Seems like I was wrong all these years. I thought of posting this here because some people here might be thinking glass is a liquid.
