Start a fern collection, and call the tank a Wardian case.
Mist with rainwater only, if you have hard water. I learned that the hard way when I was trying to keep a collection (in of all places, the moonscape of El Paso, TX) The more I misted, the worse they looked. Eventually they all perished. Fortunately, many ferns sold in small pots are inexpensive. Miniature orchids are nice too - but that's way out of my budget.
You could, of all things, put a fish in there.
Does it hold water?
