Children's museum

A couple of weeks ago we took B to the Children's Museum on a dreary Saturday. It was a fun trip despite the deceitful advertising (since we didn't see a single "child" pinned up on display anywhere). There was lots to do and things to touch so all in all it was a good day and it gets me thinking, if a "Children's Museum" is simply a bunch of stuff that a kid would like to play and interact with, what would a "Man's Museum" have in it? Food for thought.
