COSI - The Center of Science and Industry by little_liebchen
It has relocated since I've been there. But it's a fantastic activity for families. It's very kid-oriented, but adults will enjoy and learn from it too.You can do stuff here like watch rats play basketball, learn about animation, study the ocean, and travel back in time (well...kind of). But come on, I had you interested at the mention of basketball-playing rats, didn't I? Admit it!
Anyway, since I have no kids of my own, I haven't been there in ages, but I really loved going there when I was a kid.
