[Magdalen] Coffee Cups vs Wine Glasses

[Lynn Ronkainen]

Ah Allan, I love your post (perhaps because I am, at the moment, drinking an 
afternoon wake-me-up coffee at the computer (where I've managed not to ever 
spill and it is still in a mug as I type).

...and now for a few observations <gdr>

Allan> However, it looks to me that both the cup and the glass are half full 
in the experiment.

Lynn: Ah, so it's a philosophical statement not a physics thing! <more gdr>

Allan> Anyway, how many of you (like me) would have picked the wine glass as 
having less stable liquid, because of the way it sloshes around in the
round container?

I would have picked the wine glass not due to possible scientific posit (or 
experiment) but due to the focused carefulness of the action of carrying a 
wine glass under the usual circumstances of it being done while drinking an 
alcoholic beverage (full, semi-full, under the influence, walking, standing, 
etc, etc, etc), a 'learned behavior' that would carry over regardless of 
contents.

Is 'stable liquid' in the eye of the beholder, the taste buds of the 
consumer or the latitude of the scientist?

Lynn

ps. admitting I've not yet read details of actual experiment

single bit of talent left and could say, "I used everything You gave me."
