Wow, this place is amazing. It's a bit hard to describe...on the one level it's a science museum, but it's really an institution that has launched the hand-on science museum, and serves as the source for many exhibits you've seen elewhere. It's in a great location on the embarcadero (close to lots of other things to do, places to eat, etc.), and extremely compelling...even after two days there in a row I could not pry my kids out. I wasn't alone, even at closing time it's packed with kids and parents stuck on various exhibits, etc. waiting for just a few more minutes to try things out. Really amazing hands-on spot, worth a visit and re-visit.
