The Germans are taking life under the bubble to a whole new level.

In 2004, a Malaysian company turned a large hangar originally meant for airships (think blimps) into an indoor tropical paradise just outside Berlin.

The hangar -- larger than 10 American football fields and tall enough to fit the Statue of Liberty -- was built in 2000 to house airships designed to carry extra large pieces of cargo. When that company went bankrupt, the Malaysian firm took over.

Now the hangar hosts a lagoon, a 600-foot long beach, the world's largest indoor rainforest (with a half-mile hiking trail), a spa, bars, restaurants and a 198-room hotel, among other other things.

Parts of the roof have even been modified to let in ultraviolet light, allowing sunbathers to get a natural tan.
