Ask anyone you know who grew up in the Bay Area about the Exploratorium, and they’ll likely be able to share stories of class trips and seeing their hair stand on end at an installation about electricity or fun-house mirrors that taught about optics and visual perception. This is not, however, a museum simply for kids—though curious kids will definitely be entertained while learning. Instead, its exhibits aim to raise the scientific literacy of visitors of all ages, by providing engaging, amusing, and hands-on experiences. Long housed at the Palace of Fine Arts, the Exploratorium opened in its current, and much larger, space on Piers 15 and 17 in 2013. One advantage of the new waterfront location is the North Gallery and its outdoor spaces, focused on environmental phenomena like the wind, rain, and tides. The completely dark Tactile Dome and the disorienting Monochromatic Room may prove not just the highlights of your visit to the Exploratorium but the most memorable, or at least strangest, moments of your time in San Francisco.
