Insider guide to San Francisco’s Exploratorium

The Exploratorium on Pier 15 in San Francisco is a wonderland of experiment and investigation – and quite a bit of play – exploring science, art and human perception. Attempting to offer a guide to the Exploratorium is like herding kinetic molecules in a swirling vortex of mechanics, magnetics, chaotic pendulums and gravity wells, which is probably one of the museum’s exhibits.
