Template:Technical Block A bubble column is a block generated by placing magma blocks or soul sand in water. Bubble columns push or pull entities in certain directions.

Occurrence

Natural generation

When generating the world, caves, ravines and underwater ruins generate below the water surface. When lava generates in the former two, some lava is converted to obsidian, and some to magma blocks, which create bubble columns. All bubble columns generate bubble column blocks until the column reaches the surface of the water or a solid block above the magma block.

Post-generation

When a magma block is placed underwater, a whirlpool bubble column is generated.

When soul sand is placed under source water blocks, an upward bubble column is generated.

Obtaining

Bubble columns cannot be obtained as an item,‌[Java Edition only] and can be placed only by a block-placement command such as /setblock.

In Bedrock Edition, it may be obtained as an item via inventory editing.

Usage

A player or any other air-breathing mob can enter a bubble column to replenish their air supply, at the same speed that they would when they leave the water entirely. Water-breathing mobs avoid bubble columns; they die if trapped in one. A bubble column is destroyed when moved by a piston. When creating a bubble column, all blocks above must be source blocks.‌[Java Edition only] This requires either naturally generated water, or for the player to place a water source for each block they would like the column to reach. Placing a kelp plant up a flowing water column changes any flowing water blocks into source blocks. Bubble columns can also be created in downward flowing water,‌[Bedrock Edition only] however this causes all water to be converted to water source blocks. Bubble columns do not propagate through waterlogged blocks. The height of a bubble column is limited only by the water's surface or by any obstructing blocks underwater.

Whirlpool

Whirlpool bubble columns can be seen by air bubbles wandering downward. They drag entities downward. A boat ridden over a whirlpool shakes and eventually sinks if kept above the whirlpool for too long. This has a vertical range of 86 blocks.

Upward

Upward bubble columns can be seen as vertically rising air bubbles. An upward bubble column accelerates entities upward. The longer an object rises through the bubble column, the faster it travels. At high enough speeds, players and entities can be launched out of water by several blocks. Sitting on the surface above a rising bubble column causes entities to bounce upward repeatedly by about 1 block.

Transport

Entities move at a speed of approximately 15 blocks (meters) per second when inside a bubble column. This equates to a speed of 900 blocks per minute, albeit only vertically.

'''Ghast tears''' are items [[Drops|dropped]] by [[ghast]]s. They can be used to make potions of [[Regeneration]] and [[end crystal]]s.

== Obtaining ==

=== Mob loot ===
[[Ghast]]s drop 0–1 ghast tears. [[Looting]] increases the maximum ghast tears dropped by one per level, for a maximum of 4 ghast tears with Looting III. Looting also works when knocking back a [[fireball]] with an enchanted item.

'''Chains''' are metallic decoration [[block]]s.

== Obtaining ==
=== Breaking ===

Chains can be mined using any [[pickaxe]]. If mined without a pickaxe, it drops nothing.
{{breaking row|Chain|Pickaxe|Wood|horizontal=1}}

=== Natural generation ===
Chains generate in [[bastion remnant]]s and sometimes in [[ruined portal]]s that generate in the Nether. They always generate above [[magma cube]] spawners, also found in [[bastion]]s.

Chains can also generate in [[mineshafts]]. They generate on the sides of a wooden bridge (a mid-air corridor) when the distance between the bridge and the highest solid block below it is higher than the distance to the lowest solid block above it. Chains here generate vertically in a pillar between the bridge and the ceiling. The lowest block of the pillar, connecting the chain to the bridge, is always an [[oak fence]].

=== Chest loot ===
{{LootChestItem|chain}}

=== Crafting ===
{{Crafting
|B1=Iron Nugget
|B2=Iron Ingot
|B3=Iron Nugget
|Output=Chain
|type=Building block
}}

== Usage ==
Chains can be used to suspend [[bell]]s, [[hanging sign]]s, or both types of [[lantern]]s (normal lanterns and soul lanterns), as the chain texture connects to the chain of the lantern seamlessly as if it were part of it, and it connects the hanging sign chains together. Chains do not require a supporting block to be placed whether it is on the top, next to it or at the bottom. It can exist completely free-standing in mid air<ref>{{bug|MC-178791}}</ref> and it can be rotated. Chains connect horizontally or vertically, but not across different orientations (so a chain with N orientation does not connect to a chain with E orientation in the adjacent block).
Horizontal chains one block above a surface may be walked over. Horizontal chains two blocks above a surface prevent players from traveling past them. Vertical chains block travel if targeted directly, but may be skirted.

Precision is required, but chains can be walked on, allowing for inconspicuous, although somewhat costly, bridges.

Chains can be pushed by [[piston]]s without being broken.
