Waterfall

Waterfalls are created when water touches a half block (1 foot high block), which can be created by using a hammer. Lava and honey can be used in the same manner to create "lavafalls" and "honeyfalls". 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; however, lavafalls will emit light like lava. Therefore, players will not drown if they are under a waterfall, will not be inflicted with the On Fire! debuff and get damaged in lavafalls, or get the Honey buff in honeyfalls.
