On our way to Tuscon the previous day, we had noticed signs for tours of Biosphere 2. Remember that? From the 90's? So, on day 19 we took another unexpected side trip that turned out to be a fascinating place to see research in action and learn about ecology, various biomes, water cycles, carbon & climate studies, conservation, history, and, well, Biosphere 1!
Lots to read and look at and do while waiting for our tour to start

I can't remember if the wind was from a machine or if this was
where we were changing rooms with varying air pressure.
Maybe Matt or one of the kids will come along and remember...
Learning how the "lung" worked to accomodate air pressure changes
within the sealed building as temperatures rose and fell
