There's no particular reason to want to continue that metaphor more directly. Only mathematically precise metaphors have that kind of power.

Well, is it better to continue a vague analogy, or mix your metaphors and end up with something that reads oddly? ("Evaporative cooling" leading to an explosion? Isn't freezing the relevant phase transition here?)

I'm just nitpicking language here, so maybe I should stop hijacking the thread. ;)

When I followed the link to the page, I watched the gif of a condensate cooling down; at a certain point, when enough of the 'red' (warmer) points had disappeared, the white column seemed to surge or 'explode' upwards.
