On reflection, I'll take C).. tho I might phone a friend first ..

Not quite .. I've been reading online boards quite a while .. just gloss over them now :) But yeah wasn't a bad effort at all !

It's not even that simple - it's not just the phase change, 2 degree liquid water will "float" on 4 degree liquid water... This is stuff that Hammo really could explain to you much better than I could... But I'm not expecting him to in his current mood... big (and no, "current mood" is not an alternator efficiency joke ;-) ) -- "Everything you love, everything meaningful with depth and history, all passionate authentic experiences will be appropriated, mishandled, watered down, cheapened, repackaged, marketed and sold to the people you hate."
