welcome to 5th grade science.

Glass is an amorphous solid not sure what it means but wikipedia and snopes see mto support this. Bill Nye classified it with jello.

For proof check the windows of a really old building and see that its thicker near the bottom than at the top.

One common misconception is that glass is a super-cooled liquid of practically infinite viscosity at room temperature and as such flows, though very slowly. Glass is generally treated as an amorphous solid rather than a liquid, though different views can be justified since characterizing glass as either 'solid' or 'liquid' is not an entirely straightforward matter [1]. However, the notion that glass flows to an appreciable extent over extended periods of time is not supported by empirical evidence or theoretical analysis.
What's to discuss? Use Wikipedia next time.

This is a popularly held misconception. That has to do with the manufacturing methods.

Best science lesson is to be taken to the Corning factory in upstate NY where you can walk through the factory while they're blowing glass. Sweet.:)

They make the lenses of giant optical telescopes, and have on display some of the rejected ones. They have to be super-perfect or they're garbage.

Woot, four!

I recall something about there being 5. The extreme opposite of plasma... don't remember what it was called, but I think it had something to do with einstein.
