Water in Fountain of Nations or It's A Small World
Just wanted to post this. I learned this recently so I figured I'd share it incase there are others out there that do not know it.
All the countries that are represented in the World Showcase brought water to the Fountain of Nations (the fountain in the front of Epcot) and put water in it before Epcot opened. Since that day, the water has just been recylced in and out of it. So the original water really was from all the nations all over the world and it really was a fountain of nations.
The Same thing happened with It's A Small World. Walt and the Imagineers asked every country that was represented to bring water to the attraction. Water was brought and the water has been cycled through just like the Fountain of Nations.
