I know what you're thinking, where is there water in Spaceship Earth? Apparently water does exist at some area of the attraction and a Disney spokesperson stated that the "minor water leak" occurred in the morning and the ride had to be temporarily shut down but the ride is expected to be open for Monday.
Spaceship Earth takes place inside the geosphere and allows guests to travel in time to see the history of communication from the Stone Age to the Computer Age. Upon your return to Earth guests have the chance to design the kind of future they want to live by using the touch screen within their ride vehicle.
Epcot guests posted video of the leak on Sunday on social media.
