Let's have a knock down drag out fight about this, shall we?
I mean it is so important..it has to be decided now.
We could get more water, we could get a smaller/bigger glass (beaker or boiling flask, I prefer erlenmyers but we can discuss the merits of each later..) and we could use a larger or smaller cooling/heating system (Co2 or a good bunsen burner)
BUT, the truli important question is
what kind of coffee do you plant to put in that hot water? Or ice tea mix if the water is cold?
Would you have too much or too little of whichever beverage? Would Jesus be handy to turn the water into vino and get the multitude of angry pessimist vapers drunk and docile?
What does it all mean, Mr Natural?
No, we shall not. I don't fight on the internet, I like you, I tend to think there's no wrong way to see the glass and I need to get my skinny .... off to work to go properly size some systems.
Also, I like vanilla lattes.
