So It's Kinda Like They're Sweating All Over Each Other

From Boing Boing:

While Japan demolishes one of its famed indoor "outdoor" simulacradomes, a Zeppelin hangar in Brandenburg, Germany is transformed into a massive indoor beach resort. From The Guardian:

The scale of the operation puts one in mind of Willy Wonka's chocolate factory, or a Martian colony, or other things that don't exist in real life. They have trucked in 30,000m cubed of soil and 500 plant species for their rainforest. The speakers which broadcast insect noises are shaped like rocks. And the building itself, it goes without saying, is extraordinary, the biggest inside of anything you will ever see. It makes your head spin. This place doesn't just have a climate. It has weather. As the place fills up, the extra moisture in the air condenses on the roof. It starts to rain a little bit." (my italics)

So "sweat" in German is "rain"?
