Engineer: The glass is twice as big as it needs to be.

My mother in-law is a lab scientist. She says this is accurate.

The beaker is always full, when it's half full of water, it is also at the same time half full of air. THE GLASS IS ALWAYS FULL

Realist: who’s cleaning all these glasses?

Opportunistic Lab Intern:

“While you’re all debating if it’s half full or half empty I drank it. Now it’s empty.”

Ah, it's this time of the year again. (version 3)

Scientist Russian Roulette: Drink the mystery breaker. They all have water, except for one that's hydroflouric acid.

I thought the half full, half empty thing. Was about the flow of water. If you're emptying the glass, at some point the glass will be half empty. If you fill the glass, at one point the glass will be half full.

Ahh found that label!:

99.985% Pure.

Nitrogen (N₂): 39%

Oxygen (O₂): 10.5%

Argon (Ar): 0.465%

Carbon dioxide (CO₂): 0.02%

Water (H₂O): 50%

After a long romp, a fairly new g/f went into my kitchen, grabbed a 1 gal bottle of white vinegar from the fridge, poured herself a glass and tried to chugged it while I was still in bed recovering. -She had the nerve to think I tried to poison her (for half a minute)!

Read and use labels. lol

That beaker does not look half full to me. Many like 1/3rd full, or at least somewhere between that and half full.

Engineer: the glass is underutilized/over-sized

Management: Lets hire a consultant to investigate the value proposition of downsizing glasses and discuss the results over a company expensed dinner.

Topologist: that is a plate

I just watched this so i have to post here https://youtu.be/0EytSWiKrFg

Engineer: the glass is twice as big as in needs to be.

It's not 'is the glass half full or half empty'.

The question is 'why is the glass?'

Once you know this, the first question is easy to answer.
