SAN FRANCISCO, CA - MARCH 07: Visitors walk across the "Fog Bridge" at the Exploratorium on March 7, 2014 in San Francisco, California. The Exploratorium's Fog Bridge, created by Japanese artist Fujiko Nakaya, is a 150 foot bridge that links piers 15 and 17 that uses water pumped at high pressure through more than 800 nozzles along the bridge to create a misty fog-like environment.
