Check out the construction of the Exploratorium's building at Piers 15 and 17 from a different vantage point—a boat about 100 yards off the back of the piers. Listen to the sounds of underwater marine life as well as the din of construction above the water, both picked up by a hydrophone and mixed with the sound of an outdoor exhibit at the Palace of Fine Arts, for a unique view of the construction.
