It is a giant warehouse on Pier 15 that is newly moved into the facility and apparently greatly expanded. Wide range of scientific principles in easily demonstrated, hands-on format. Kids were loving it. Multiple live demos going on, at least on Saturday. Favorite quirky thing for me was the toothpick creation that was HUGE and represented all of San Francisco, taking 37 years to complete -- amazing. Oddest thing was a wooden structure in the behavioral science area that displayed the meager belongings and a biography of residents of a psychiatric hospital 50 to 100 years ago, comparing treatment then to now. I got the point, but it was still creepy. I did not eat there, but the cafeteria looked fabulous. Great view of the Bay. Worth the $25.
