Waterfall

Waterfalls are created when water touches a half block (1 feet high), which can be created with a hammer. Two types of waterfalls are possible: a running waterfall is produced when a half block is at the edge of a liquid body; and a stationary, vertical waterfall is produced when a body of water is only supported by a half block. Waterfalls are visual effects only; they do not drain anything from the liquid source, nor do they have any effects on players, creatures, environment, or furniture.

Lava and honey can be used in the same manner to create "lavafalls" and "honeyfalls". Similarly to waterfalls they cannot inflict On Fire! or the Honey buff, but lavafalls will emit light like lava. Both lavafalls and honeyfalls will also appear to flow at greater viscosity than water.
