A few hours (honey) versus several centuries (if ever, for glass)? You'll
have to do better than that. Almost any solid can undergo plastic deformation,
given a large enough stress over long enough time. That doesn't make it a
liquid.

Glad to. Anyone who thinks a flat piece of material qualifies as a
"container" needs some help badly. A container is something that *contains*
something else, not just supports it. If an object doesn't have a definable
"inside," it can't contain anything.

Just curious-- Why? This type of man needs the most help of all.
