Today in questions you never thought you'd find on a football messageboard;

You know when you fill a glass so full that the liquid sits higher than the top of the glass and kinda curves over but doesn't spill over the edge? Like a globular horizon?

Does that have a name?

Meniscus. (Sp)

Meniscus?

Brimfull - the point of overflowing (teeming)

A quick google of meniscus leads to some anatomical body horror.
It's not to say it's wrong, but it's not the top result!

Meniscus is a knee cartilage
No idea what that convex surface is called, but it's surface tension that causes it.

Convex meniscus.

My apologies it is Indeed called a 'convex meniscus'

Far out, thanks!

You’ll never see it in a pub.

Chopping onions and convex meniscus on here tonight - what a time to be alive

If I recall, mercury makes a convex meniscus, as do a lot of molten metals, due to the way the molecules all attract each other fiercely. A bit like a 4-4-2 formation

Meniscus - the only correct way to have your water bottle filled during phase 1 military training whilst on inspection.

No meniscus = pain. (In the good days before PC took over training).

When not on inspection, best be drinking it to stay hydrated.

This is what I remember it from, being taught how to read a mercury thermometer at school (and then a thermometer inevitably getting smashed and the teacher trying to keep the kids away from the blobs of mercury).

A decent pint of Guinness gives the answer

Any fluid displaying surface tension (eg water) can create a meniscus.
