This is actually true, regardless of chips settling in a potato chip bag. Physics is clear that the glass is always full of something, a combination of fluid and air, so never half-full. But that's just me being pedantic.

What if I pull a vacuum in the glass? Can it be full of vacuum?

No, because vacuum is not a "thing" but rather an event, the result of an action upon the object; whereas the water and/or air are actually things/objects filling up another thing/object (the glass).

If you place a miniature vacuum generator inside the glass, which then creates a vacuum effect within the glass, then you have a vacuum in a vacuum. Which isn't then a vacuum since a vacuum has an absence of matter whether gaseous, liquid or solid.

It's simple, really.

Hence the phrase: "being a smart ass doesn't happen in a vacuum."

What about the virtual particles that form in the vacuum within the glass?

As an engineer, I'd say that the glass is twice as large as it needs to be but the bag is not.

What if it is your beer glass and are looking at the bottom?

Not so much 1/2 full 1/2 empty as it is a problem.
