How? You mean they've never been absolutely full? Like when I drink even just a sip from it it's already not full

[removed]

Its always at least full of air

Oh, sorry, blame it on my stupidity and lack of creativity lol

There Technically IS water in the air. I will fight for your right to say this statement, sir.

I bet you there's at least one drinking glass inside a vacuum chamber out there. If anyone reads this who has a vacuum chamber then you should put a drinking glass in it just to prove OP wrong.

...Unless you want to claim that 3d space is a substance. Which I'm not qualified to argue about

Underrated comment

full

/fo͝ol/

adjective

1. containing or holding as much or as many as possible; having no empty space.

A glass holding air could contain more if the air were pressurized, therefore it is not full.

Wait till the guy with a turbomolecular pump in his basement sees this.

Touché my friend!

However... Having no empty space", you yourself posted as being full too?

But agree to an extent as well with your argument. Which would also mean that they're never full because most things can be compressed under extreme pressure. For example in a black hole...

Haha I thought this was Shower Thoughts?! Not Hey someone make this guy a liar thoughts?!

I did think of this but took a gamble that the likely hood is very small for a drinking glass.

I’m not qualified to argue about the contents of a vacuum either but I’m gonna throw this out there: https://en.m.wikipedia.org/wiki/Quantum_fluctuation

Some of us just like to cause trouble :D sorry!

That's the thing about semantic arguments; no one is ever right because definitions aren't rigorous. Words mean only what they are understood to mean, and a glass full of air is understood to be empty.

Ya actually this sub is primarily people saying things and other people trying to poke holes in them

When you breathe in, are your lungs full?

Yes, because lungs are meant to hold 1 atm air. Glasses are meant to hold liquid.

You can put anything you want in glasses. Pens, food, toenail clippings

This sub is people mostly making obvious general statements or reposts, like all other subreddits.

Is this not a new thought?

The same thing applies to water or any other material you fill it with.

Then 'technically' no glass in the world has ever been full.

Never say never but yeah that’s the point if you really wanna be that picky

Are you new? This sub is basically make op a liar

Reminds of when I argued that a hole is only a hole if it goes all the way through

That is not what ANYONE means by "full" in this context. This sub needs to fucking learn how language works.

Did you guys never put a cup over your mouth and suck a vacuum so it sticks to your face? I thought that was a pretty universal childhood experience!

Is this the little kid that says "It's tomorrow now!" after midnight at a slumber party?

It’s it’s in an unpressurized environment it will be impossible to hold more, therefore even if it’s an unpressurized environment under that definition it would still be full.

This is the valid argument to OP

by extrapolation of your point nothing is ever empty and I agree

If the air were colder, it would also be more dense and therefore more would fit in the glass. But this whole discussion is pointless. It's a semantic argument, and saying that things are always (or never) full makes the word 'full' meaningless. Neither argument aligns with how the word is used, therefore they are both wrong.

[removed]

LOL, no. It has occurred to many people.

Put a glass in the plain of um existing

[removed]

This is exectly how language works! You saying "not what anyone" is already a statement that You yourself don't know how language works. One person thought outside of everyday context thus some think that way. Incorrect use of anyone much?

What it means for space to be empty or full. From physics standpoint even in vacuum there is still quantum foam.

Except water is incompressible

water is incompressible

Not with that attitude

[removed]

With air, Yea

With Liquid, not always

With solid, At best 50% on occasion with ice cubes

The glass is always full, reguardless if it is full of water, air, or water and air.

I’d say a glass is full when it overflows upon adding more fluid

https://youtu.be/egEraZP9yXQ

Is it though? It's denser at extreme depth. I'm trying to get my tired brain around this and failing.

So ... it's full just below the pressure that causes it to break?

I prefer to call it ‘lets correct, the shower thoughts of those needing enlightenment.’

Fill your cars combustion chambers up with water and tell me if it compresses lol

So now we have to say “of this very specific liquid” every time we use this phrase, rather than assuming everyone inherently understands?

Sometimes I really do believe humanity is getting dumber.

If the air were colder it’d be a differently pressurized environment, so within any specific environment it’d always have the potentiality to be full. So even with your semantics I think OP’s showerthought is accurate in that sense. But not in the sense of using vacuum suction to remove the air.

Of course not because the conrods will bend first. But as an awake person I can now remember that water is indeed denser at great depth (to an extent that is reflectee in the anatomy of the fish that live there). So it is compressible it's just not easy.
