The MIT museum isn't very good. It is a science museum for adults, but it is too passive an experience for the patron. I recommend the Exploratorium in San Francisco instead as the science museum for adults.
I've only been to a play (staged reading) at the new one but, in general, I'm not sure how interested most adults are in interactivity. I've been to the Exploratorium for an event and it was fun. (Having those sort of distractions are nice when you're tired of feeling like you need to speak to people at an event.) But not sure I'd have made a trip there otherwise.
