I suppose this is as good a thread as any to ask this question:
If you hit pitch hard enough it shatters. Does this mean that if you hit water REALLY hard it might shatter? ![:D](./images/smilies/biggrin.gif)
The obvious answer is no, but why?

Quote: Originally posted by Sedit ![](images/xpblue/lastpost.gif) | The windows to the attic in my old house where well over 150 years old and there was an obvious bulge at the base of them. They where not thicker but
there was a very obvious bend in them that looked exactly how one would expect it to look if it was a slow moving liquid. I really don't think they
where made like this as it really looked like the glass had slumped over time. | We're sure. Please don't
perpetuate this myth. The panes were installed that way by the glazier, because it looks better and more consistent. The imperfections were simply a
result of the rudimentary manufacturing processes employed at the time. Modern glass panes are much more uniform due to automated process control,
other more advanced technologies, and more rigorous quality control.<a

windowpanes are thicker at the bottom than at the top. The variations in thickness of antique windowpanes has nothing to do with whether glass is a
solid or a liquid; its cause lies in the glass manufacturing process employed at the time, which made the production of glass panes of constant
thickness quite difficult. <img src="../scipics/_ext.png" /> | </a>

You can. I know that the window glass is a myth (thicker at the buttom at extremely old windows), but glass has a viscosity of about 10 ^ 20 mPa*s at
room temperature. So it could be observed in some million years (but not in hundred as claimed by the original myth). |
When I told this to my mom, she said (sarcastically), "Maybe that's why mountains point up, millions of years ago they pointed down".

I was hoping you were going to tell us another drop fell.
