Yes, I realise that, but the cappings would have been weakened if it
was warm, hence the honey would be able to ooze.  Also, warmer honey
(as I am sure you have noticed) oozes more easily than cool honey.

So what you are saying is that those wrinkles in the top of the
capped honey are purely decorative???  I have often wondered, as
humans (and most other animals) are air tight (more or less) how come
we don't blow apart when presure drops???
Honey is denser than water (did you notice this??) and water dosen't
change noticibly in volume in most atmospheric drops in pressure,
unless they contain a good deal of air, in which case bubbles form.
But I wouldn't have thought there could be enough of a drop in
pressure to blow the cells apart as described.  If you have
supporting information, please let me know and I will happily
acknowledge that I am wrong.
 
Also, yes, honey will lose moisture to the atmosphere, if it is warm
and dry, and the air is moving.  On a warm still day, whether it is
humid or dry, the honey will not lose any moisture (or absolutely
negligible amounts).  On cool days, it acts the same as on warm days,
except that it hardly ever LOSES moisture.  If you leave honey open
in a fridge, it will take in water.  (I have seen this myself...)
But yes, as you said, Steven (or was it the other guy) that was a
good answer.
