The price was a little steep, even after the military discount my sister got us. I'm glad I got to go - but it was one of those places you go to once and don't need to go back to. So I won't be visiting again - unless I have a friend in town dying to go! ...it was still interesting though, don't get me wrong.
For those of you not familiar with Biosphere 2, here is the 411.
Biosphere 2 is a man-made closed ecological system in Oracle, Arizona built by Edward P. Bass, Space Biosphere Ventures and others. Constructed between 1987 and 1989, It was used to test if and how people could live and study in a closed biosphere, while carrying out scientific experiments. It explored the possible use of closed biospheres in space colonization, and also allowed the study and manipulation of a biosphere without harming Earth's. The name comes from the idea that it is modeled on "Biosphere 1" - Earth. (source)
And now for the pictures...
This is inside one of the "lungs." Basically the lung has a rubber thing inside (the black part) with a disc thing in the middle and it rises and lowers as the pressure in biosphere 2 changes.
The lung is encased in a large white dome - which you see below on the left.
The picture on the right is the outside of the Rainforest section. It was a jungle in there!
There was even an ocean!

...And I shall leave you with this...
