I was just about to post this...crazy. that's what happens when red sea gets involved...lol. jk.

Reynolds may very well be the Red Sea of public aquariums.

Well, thats just what Ive read.. Someone said that from PETA
I mean they have no chance and so on.. but thats what they said

I saw on the Peta site, Peta Germany was exploring legal action against this death trap hotel.

That's odd. PETa is usually all about taking peoples animals away and killing them, are they worried that more hotels will step on their turf?

Such little understanding of what PETA accomplishes. I thought this forum was above all this nonsense.

PETA is not an animal welfare organization.

what did PETA accomplish? Brainwash more people into believing in their non sense that did nothing good to the animals they are “protecting”. In 2011 alone they euthanized 84% of its animals claiming that they are “un adoptable”. Could go a whole day talking about their nonsense but I do not want the tread to get shut down and sidetrack it.

PETA is no friend of any pet owner.

Interesting read, didn't know about PMMA's neat quirk.

"The phenomenon behind this is called creep rupture—the disentanglement of the molecules of plastic over time, at a stress level significantly below the yield strength—yes, below the yield strength—of the plastic. "

Holds some credence to the Japanese installer story earlier in the thread about not sharing their secret technique.

Update:

US company to send team to look into Berlin aquarium rupture

A U.S. company that helped build a huge aquarium in Berlin says it is sending a team to investigate the rupture of the tank, which sent a wave of debris, water and tropical fish crashing through the hotel lobby it was located in and onto the street outside

That is a bit unexpected.

Thinking about those pictures, that aquarium in Germany could have a higher fluid column height than the enormous tanks in the Georgia aquarium with whale sharks etc.
The only thing that matters in terms of predicting the fluid pressure is the height and weight of the water above it, so it looks like a very ambitious design in terms of expected stress. Even more than a tank with whale sharks in it.

From Georgia aquarium....
"and one of the largest viewing windows in the world at 23 feet tall by 61 feet wide and 2 feet thick" That window goes about to the water surface as I remember so yeah. It's "only" like 20-25 ft (~8mof water pressure over it.
The AquaDom according to the above article...
"AquaDom in Berlin, Germany, which has a 25-meter-tall cylindrical aquarium"
Not just more, like 3x the fluid pressure at the bottom.

So if that figure is referring to the column of water, then 3x the water pressure at the bottom of the AquaDom vs the exhibit in Georgia with whale sharks. Mindblowing.

Broken pieces laying about in the aftermath looks way to thin for 80 foot depth lol , rip fishes

To blame this on the cold weather makes no sense.

First off it inside a hotel, which is heated. Secondly it's been there for 20 years. So in the last 20 years it's never been that cold before?

Highly unlikely it was because it was cold outside.

My exact thoughts.

I don't know. Somehow climate change must be to blame.
