That is cool that they have a reciprocity agreement with the other museums. You should get a lot of use out of that membership! We have a small museum in the town where I grew up, but it is a very hands on science style museum. I used to have my grandma take me there all the time. It was one of my favorite places as a kid. They do rotating displays on the upper level too. About a decade ago or so they had a couple of the terra cotta soldiers there.
That is cool! This one actually had them about a decade ago or so also - but I never got to see them.
There is a great science one in Helsinki I took Smallsteps too about three years ago and then again a couple years ago with my wife as well, but we will definitely go back this summer for sure. Fun for adults too - can make racing cars! :D
That does sound like a good time! Our local one does a lot of art displays along with the science stuff. I know one year they had a precious gem display and I was trying to get to that one.
