It is a very interesting museum. The day we were there, the glassblowing display was offline, but there was still a lot to look at and things to do. Some of the collections can be viewed pretty quickly (unless you are really into looking at all of the details, of course), there were some very nice glass-as-art pieces, and some cool interactive things.

I'd love to go back sometime just for the hands-on make-your-own experience.
