The other reviewers are right to an extent--my first impression of the museum left me appalled (esp. the smell of the carpets). I thought we would be out within an hour. But my husband (a Berkeley engineer) insisted there was a lot of interesting stuff. We ended up spending several hours there and, most surprising of all, my kids (4 & 6) LOVED it. If you belong to another member science museum, can get in free, and have a rainy day to spare, it's worth a few hours. The experience is the exact opposite of the Children's Museum, which we visited the following day. The CM is all glitz, but seems designed more to impress parents than to amuse children (i.e. parents everywhere trying out things and attempting to interest bored children).
