How much water is in the Outer Bay Waters exhibit?
The Outer Bay exhibit holds 1.2 million gallons (4,542,494 liters) of sea water. When it was built, the main view into this exhibit was the world’s largest window, 56 feet long and 17 feet high (about 17 m long and 5 m high). It was welded together seamlessly from five pieces of acrylic 13 inches (33 cm) thick.
