Fujiko Nakaya's Fog Bridge Installation at San Francisco's Exploratorium

Japanese artist Fujiko Nakaya created 'Fog Bridge #72494,' a permanent public artwork installed in 2013 at the Exploratorium museum's waterfront location in San Francisco. The 150-foot-long bridge features over 800 high-pressure nozzles that generate mist for approximately six minutes every half hour, responding to real-time weather conditions via an anemometer. Nakaya, who has worked with fog as an artistic medium for over four decades, designed the installation to interact with San Francisco's natural fog, known locally as 'Karl.' The artwork uses desalinated bay water and was temporarily deactivated during California's 2014 drought for conservation. Nakaya's artistic focus on fog stems from her family background—her father, Ukichiro Nakaya, was a prominent snow physicist who created the first artificial snow crystal in 1936.
