Waterfall

Waterfalls are created when water touches a half block, which can be created with a hammer. They are visual only, having no effect on the player, creatures or furniture. The color of a waterfall will match the normal color of water in the biome in which it is located, unless the waterfall is created using a rainbow brick. In the case of the rainbow brick, the color of the waterfall will change to match that of the brick. Blood moons will turn waterfalls red, just as they turn normal water red.

It is also possible to make "lavafalls" and "honeyfalls" using the same method.
