How do you empty and fill a Weather Ball Barometer?

Question

I'm moving and I've had this for years. I no longer have the instructions and can't figure out how I got it filled, or how to empty it so I can pack it.

In case you don't know what it looks like there is a picture of a similar one here http://www.enasco.com/product/SB33482M
