I read something this morning in last week's issue of the All Ears Net newsletter- my favorite email once a week- about the fountain that sits just beyond Spaceship Earth (the actual name of the giant golf ball thing, in case you didn't know).
Before the park opened on October 1, 1982, representatives from 23 countries and regions collected water from their lakes, streams, rivers and seas. These were not just the countries that are represented in the World Showcase! Each country kept their vessel of water and then during the opening ceremonies, in what was called the "International Ceremony of the Waters", one by one, they poured their water into the fountain to symbolize the international understanding and cooperation for which EPCOT Center stood.
