A bubble column is an air-providing vertical water current. It is created by magma blocks and soul sand and, depending on the block used, will either pull entities downward or push them upward, respectively.

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

In Bedrock Edition, it may be obtained as an item via inventory editing, add-ons, or bugs.

Whirlpool bubble columns may appear naturally when magma blocks generate underwater, in clusters on the floor of aquifers, or as part of ocean ruins and ruined portals generated below the water surface.

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.

A bubble column is created 20 game ticks after placing a magma block or soul sand, and is destroyed 5 game ticks after destroying the magma block or soul sand. A bubble column is created or destroyed in all water source blocks of the bubble column simultaneously.

Players and air-breathing mobs can enter a bubble column to replenish their air supply at the same speed that they would when they leave the water entirely. However, the slower mining speed when underwater still applies to players inside bubble columns. Water-breathing mobs avoid bubble columns because they suffocate if trapped in one. A bubble column is destroyed when moved by a piston. Bubble columns propagate only through water source blocks, stopping at any flowing water or waterlogged block. The height of a bubble column is limited only by the water's surface or by any obstructing blocks underwater. In Bedrock Edition, using powder snow to remove water sources from a bubble column and destroying the powder snow with flowing water creates a bubble column without water.^[1]

Bubble columns cannot be created in downward flowing water.^[2] This can be circumvented by placing kelp in downward-flowing water, which converts it into a source block.

A whirlpool, or downward bubble column, is the only type that naturally generates in the Overworld, often originating from magma at the bottom of underwater canyons. A whirlpool can be identified by the presence of 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.

Upward bubble columns can be identified by the presence of 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.

In Java Edition, entities move at a speed of approximately 11 blocks per second when in an upward bubble column, or 4.9 blocks per second when in a downward bubble column.

In Bedrock Edition, entities move at a speed of approximately 8 blocks per second when in an upward bubble column, or 6 blocks per second when in a downward bubble column.

An observer can detect when a bubble column is created or destroyed in a water source block.
