Fodor's Expert Review Exploratorium

Walking into this fascinating museum of "science, art, and human perception" is like visiting a mad-scientist's laboratory, but one in which most of the exhibits are supersize and you can play with everything. Signature experiential exhibits include the Tinkering Studio and a glass Bay Observatory building, where the exhibits help visitors better understand what they see outside. Get an Alice-in-Wonderland feeling in the Distorted Room, where you seem to shrink and grow as you walk across the slanted, checkered floor. In the Shadow Box, a powerful flash freezes an image of your shadow on the wall; jumping is a favorite pose. More than 650 other exhibits focus on sea and insect life, computers, electricity, patterns and light, language, the weather, and more. Don't miss a walk around the outside of the museum afterward for superb views and a lesson about the bay's sediment and water motion in the Bay Windows presentation.
