Space Colnel: German engineering?
b1: To me (being ¼ of a world an ocean and a language barrier away) i'd say, "no, or not EXACTLY'...
That thing was massive (world's biggest!), but it was also outdoors in < 0C temps...
Assuming it hasn't been tampered with, I bet it's some kind of structural failure...
It's not the water freezing, for sure... Water has an interesting property, just like everything else, it shrinks, but JUST BEFORE it freezes, it THEN expands (has to do with the way the H molecules align) ...
Chemistry stupes will say that freezing is it, but it's definitely NOT. (Too much water, too much motion... It might even be heated, I don't know.)
If it was IN, my prejudice and bias would just say 'yeah, it's their engineering'...
But DE engineering is a Sharp Precise Good Thing.
Porsche, BMW, Audi, etc...
Sure, all those examples are automotive, but there're others (especially in health and medicine)
SC: It appears to be in the lobby, so I doubt temperature was the issue.
b1: No no no. IT RUNS SEVERAL STORIES IN THE PLAZA SURROUNDED BY THE BUILDING.
SC: So it was outside.
b1: Yes.
BBC News - Berlin's giant AquaDom hotel aquarium containing 1,500 fish explodes
SC: I missed that when reading the article.
b1:Stupid Yanqui writing, crossed with bad Internet editing.
I thought the same thing when I first read it upon awakening...
The Accomplice had just woken up too and immediately said, "that structure's not inside."
Too much of the architectural statics of that building don't allow something something to be built inside like that.
(of that.)
Hey man, I just woke up from 2nd sleep.
It is SO nice to talk to you, first thing, in real time.
SC: The BBC states it was in the lobby as well.
Nobody's doing a good job of describing the setup.
b1: It's a cylindrical building with a big fish tank tube in the center. Something like that.
Google Earth/Maps'll show you (which I haven't used in this case.).
It's in the middle of the structural hotel. With a skylight above.
I'd call this an 'atrium.'
And then, there's THIS...
SC: War zone like footage in Berlin, followed up by what........? Barbie! There's some logic here somewhere -- I'm digging for it.
