Comparison of stone and water blocks

Liquids are blocks that can, as the name suggests, flow and spread.

Usage

There are currently only two liquids in Minecraft: lava and water.

How liquids work

File:2011-09-22 09.54.38.png

Lava seeping through one layer of dirt.

Liquids are cellular automata. The rules appear to be as follows:

Falling liquid

An air block below a liquid block is converted into a liquid block of that type. This happens faster for water than for lava (except in the Nether).

Liquids that are suspended above an open area by one block thick of material will seep through the material and drip to the floor. Lava particles that are seeping do not cause damage or start fires. This makes digging upwards safer, since you can tell if you are near a lava/water lake.

Liquid level

Each liquid block has a level value. Source blocks have a level of 0, and the maximum level depends on liquid type.

Note: The "level" value increases as the water is further from the source. A high level value means that the water is actually physically downhill.

Flowing liquids

To keep track of which blocks are actively flowing, water and lava each have a pair of block IDs. For water, there is flowing_water (8) and water (9). Water will stay in place until it receives a block update. Flowing water updates periodically and will change itself to water when it cannot spread any further.

Updating a block next to water will turn it back to flowing water so it can spread some more.

Liquid block update cases

The state of a liquid block only updates in certain cases:

  • On creation
  • If one of the 6 neighboring blocks' state changes.
  • If its own level changes

State changes that cause an update include:

  • Adding or removing a block
  • A neighboring block's level changes
  • A redstone wire switches on or off

However, generated structures never cause block updates to adjacent liquids when they spawn, so for example a cave entrance may meet a lake or ocean but remain dry until a block update is triggered. However, liquids can flow from a structure immediately when it is generated.

Liquid block update process

When a liquid block updates, it performs the following checks.

  • Check inward flow
If there is a liquid block of the same type above, set level to 1
Otherwise, reduce or increase level in steps of 1 so that it is 1 higher than the one of its 4 neighbouring block with the lowest level*
If level is increased past the max level, replace liquid block with air block.
Level cannot be decreased below 1

* This does not affect source blocks (level = 0)

  • Check outward flow
This only happens for liquid blocks of less than the max level value
Determine the shortest distance to a fall, but only scan 5 blocks distance*
If any of the directions tied for shortest have an air block, convert that air block to a liquid block with a level of 1 more than the current block*

* This means that lava will flow towards a drop that it cannot reach.

Source creation

A water block is converted into a source block if both of the following conditions hold:

  • it is bordered by at least 2 water source blocks on the same horizontal level.
  • the block underneath is a solid block or a water source block.

Lava source blocks cannot be created.

Mixing of liquids

If a liquid flows into a block occupied by another liquid, then the block turns into a solid block according to the following rules:

  • If Water flows into a lava source block, then obsidian is produced.
  • If Lava flows downward into Water, then stone is produced.
  • if Water flows horizontally into downwards flowing lava, nothing happens.
  • Otherwise, cobblestone is produced.

When determining the shortest distance to a drop, other liquid blocks are assumed to be equal to air.

A '''nautilus shell''' is an item that is used for crafting [[conduit]]s.

==Obtaining==
===Fishing===
{{main|Fishing#Junk and treasure}}
Nautilus shells can be rarely obtained as a treasure item from fishing. The drop chances of nautilus shells slightly increase with each level of [[Luck of the Sea]] on the [[player]]'s [[fishing rod]].

===Mob loot===
[[Drowned]] have a 3%{{only|java|short=1}} or 8%{{only|bedrock|short=1}} chance to spawn with a nautilus shell in their off-hand, and this nautilus shell always drops upon [[death]].

===Trading===
[[Wandering trader]]s may [[trading|sell]] a nautilus shell for 5 [[emerald]]s each, but they only sell 5 of them at a time.

==Usage==
{{IN|bedrock}}, a nautilus shell is one of the few items that can be held in the off-hand.

===Crafting ingredient===
{{crafting usage}}

=== Trading ===
Nautilus shells can be given to trident-wielding drowned with a chance for the drowned to pick up the shell and drop the trident.<sup>[''[[Bedrock Edition]] only'']</sup>

==Trivia==
*[[wikipedia:Nautilus|Nautilus]]es are animals that occupy deep oceans in the real world. However, they are absent in Minecraft and there are currently no plans to add nautilus [[mob]]s into the game.
*Because {{el|bedrock}} allows for Nautilus shells to be held in the off-hand (since drowned hold them), they are the only item in that version that can be put in the off-hand slot without having a specific function.

'''Drinks''' are a narrow class of consumable [[item]]s that can be ingested by the player in an extremely similar manner to [[food]]. However, drinks are not encountered quite as commonly as food is, and they are not nearly as integral to survival gameplay. Drinks can generally be distinguished from food from the sounds they make upon consumption, the lack of particles emitted by them, and the fact that they leave behind an empty container after consumption. They also do not require the hunger bar to be depleted, and do not affect hunger or saturation values upon use (with the exception of [[honey bottle]]s).

Drinks are drunk by holding {{control|use item}} while having the drink [[item]] selected in the hotbar or in the off hand.

Beta 1.9-pre1Liquid that is suspended above an open area by one block thick of material will seep through the material and drip to the floor. Lava that falls onto water will produce stone, instead of replacing the water.
Beta 1.9-pre5A lava block could be converted into a source block if the following conditions were met:
  • it is bordered by 4 lava sources in a cross-like arrangement
  • the 4 sources are on the same horizontal level as it
  • there is a solid, opaque block underneath it
?Lava source blocks can no longer be created.
