Minecraft wiki entry for Building_water_features, associated text: To build this fountain, start off by constructing a 5X5 frame of any material you wish, but only place blocks on the edges, so that the water has a place to flow into. Then, build a 3 block high column in the middle of the frame. Just pour a water bucket on the top of the central column to finish it off, and the water should flow down all sides. You are done!
