Liquids are blocks that can, as the name suggests, flow and spread. There are currently only two liquids in Minecraft: Lava and water.
How liquids work
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.
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 pool of water/lava.
Liquid level
Each liquid block has a level value. Source blocks have a level of 0, and the maximum level depends on liquid type.
- Water: 7
- Lava: 3 (7 in the Nether.)
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.
Still liquids
To keep track of which blocks are actively flowing, water and lava each have a pair of block IDs. For water, there is Water (8) and Still Water (9). Still Water will stay in place until it receives a block update. Water updates periodically and will change itself to Still Water when it cannot spread any further.
Updating a block next to Still Water will turn it back to Water so it can spread some more.
If you edit either type of liquid block into your inventory, they will spread when placed, since placing a block causes updates.
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
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 (as of Minecraft 1.5) 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.

{{Item

'''Clocks''' are [[Daylight cycle|time]]-telling devices that display the current in-game position of the sun and the moon. Clocks only function properly in the [[Overworld]].

Expert-level librarian villagers have a {{frac|1|2}} (50%) chance to sell a clock for 5 emeralds.{{only|java}}
== Usage ==
[[File:WatchCycle.gif|thumb|Clock animation]]
The clock dial consists of two halves, a day side and a night side. The dial spins clockwise slowly to indicate the time of day, corresponding to the sun or moon's actual position in the sky. The player is able to [[bed|sleep]] a few seconds after the clock shows exactly dusk.
The dial always shows the current in-game time when in the [[Overworld]], regardless of where it appears. This includes a player's hand, an inventory slot, a [[Crafting table|crafting grid]], an [[item frame]], or even as a dropped [[Item (entity)|item]]. For a clock to be mounted on a wall, an [[item frame]] is required.
Because there is no day/night cycle in [[the Nether]] or [[the End]], clocks do not work properly in these dimensions. Instead, the dial rotates rapidly and randomly, making them useless.
=== Piglins ===
{{EntityLink|Piglin|Piglins}} are attracted to clocks and run toward any clock on the ground, and inspect it for 6 to 8 seconds before putting it in their inventory.

== Trivia ==
* {{IN|java}}, a clock can be viewed under the item [[statistics]] page as long as one obtained a clock at some point.
* {{IN|java}}, the default resource pack for the clock contains 64 individual frames, each frame lasting about 18.75 seconds in real time (375 ticks) (1350 seconds (22 minutes, 30 seconds) in Minecraft time).
* When the time of day changes suddenly, such as after sleeping or when {{cmd|time}} is used, the clock dial spins rapidly to catch up.
* Although clocks do not function in the Nether or the End, the actual daylight cycle does continue.

A '''heart of the sea''' is a rare [[item]] that can be crafted into a [[conduit]].
== Obtaining ==
The heart of the sea must be found. It cannot be crafted or obtained by trading, making it a [[non-renewable resource]].
A heart of the sea is obtained from a [[buried treasure]]. The location is marked with a noticeable red X on a [[Explorer Map|buried treasure map]], which is found in [[Ocean_Ruins|ocean ruins]] and [[Shipwreck|shipwrecks]]. Feeding [[raw cod]] or [[raw salmon]] to a [[dolphin]] causes the dolphin to swim toward the nearest [[buried treasure]], [[shipwreck]], or [[ocean ruins]].
