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.

A '''carrot on a stick''' is an item that can be used to control saddled [[pig]]s.
== Obtaining ==
=== Crafting ===
It is possible to craft a carrot on a stick without a [[crafting table]].

}}
== Usage ==
=== Riding a pig ===
To use a carrot on a stick, the player must first [[saddle]] a [[pig]], and ride it while holding the carrot on a stick. The pig then moves in the direction of the carrot. Also, if the player holds a carrot on a stick, all nearby pigs (but not [[rabbit]]s<ref>{{bug|MC-207993}}</ref>) follow the player, but they can't breed using carrot on a stick.
To make the pig run faster, the player can press {{control|use}} while holding the carrot on a stick. This is called "boosting". Each boost costs 7 durability. If the carrot on a stick's durability is depleted, it turns back into a fishing rod.
The speed of a mounted pig is 2.42 m/s. Boosting a pig causes its speed to slowly ramp up until it reaches 2.15 times its normal speed, 5.20 m/s. Then speed slowly declines until the pig reaches normal speed again. The boost lasts between 140 and 980 game [[tick]]s (7 seconds and 49 seconds respectively), chosen randomly. No matter how many ticks the boost lasts, the average speed of pig during a full boost cycle is roughly 4.19 m/s. These boosted speeds are applied only while holding the carrot on a stick. These speeds are affected by the [[speed]] effect.
=== Enchantments ===
A carrot on a stick can receive the following enchantments, but only through an [[anvil]]:

== Obtaining ==
{{iN|be}}, glow sticks cannot be obtained by the {{cmd|give}} command. They also cannot be obtained in [[Survival]]. Cheats must be enabled to obtain glow sticks in Survival mode, or in [[Minecraft Education]].

== Usage ==
While equipped, [[player]]s can {{control|use}} glow sticks to shake them, causing them to appear bright regardless of the [[light]] level. This is only an aesthetic change, as no light is emitted to the surrounding area. A [[particle]] effect is visible until the [[durability]] runs out.

* The glowing reaction of [[Wikipedia:Luminol|Luminol]] during oxidation exists in real life. It is used for detecting blood in crime scenes.
* Players cannot enchant glow sticks with Unbreaking or Mending, despite the items having [[durability]].
* The black and light gray glow sticks use the same texture as the red glow stick.{{verify|It seems they use the missing texture instead. Was this the case beforehand, and they only started using the missing texture later?}}
