It would appear that everyone has missed the obvious here. Let's have another look and see what the obvious is.
To answer this question, we must first determine what a glass is and come to an agreed upon point of view.
In the ordinary point of view (and I stress ordinary) a glass is a vessel into which something must be poured in order to make it not empty. Now, some of those who have provided what might be mistaken for an answer, have pointed that out, while others have been almost partly right in pointing out that even if nothing is poured into the glass it is still full. Of air.
No-one has taken into account that if the glass were in a vacuum it would be said to be empty. Which, by the way, is also wrong, as even a vacuum is not perfect; there is always SOME matter, however little, present.
So, to get to my point. A glass is never full or empty. Let me repeat that. A glass is NEVER either full or empty, nor is it ever partly one or the other. How can this be? Let me explain using a simple concept. That of the surface of an object.
A glass is made up of . . . what? Well, glass is one answer, but there can be any number of other answers. For the sake of argument let us stick with glass. Now, what is glass itself made up of? Okay, glass. We could also say that glass is made of melted silica and we would be correct, but why nitpick? So, glass is made of glass and glass is full of glass. 'So what', you ask? So glass is full of glass and cannot be full of anything else!
But that is not the point. We are speaking of surface here. Now, since glass is made up of glass and is, therefore filled with glass, it stands to reason that there is but one surface to a glass and that one surface would have to be the OUTSIDE surface.
So we may now conclude that a glass cannot contain anything. Other than glass (or whatever it is made of). The most it can be is wet on the surface. Or dirty, or powdery or whatever-y depending on what you think you're filling it with.
