A bubble column is a block generated by placing magma blocks or soul sand in water (source). Bubble columns push or pull entities in certain directions.

Occurrence[edit]

Natural generation[edit]

Bubble column. (Click to see the animation)

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[edit]

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[edit]

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 or through glitching.

Usage[edit]

Info[edit]

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[edit]

Whirlpool bubble columns 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. This has a vertical range of 86 blocks.

Upward[edit]

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. Players within an upward bubble column cannot swim downwards against that bubble column's push.

Transport[edit]

Entities move at a speed of approximately 11 blocks (meters) per second when ascending a bubble column or 4.9 blocks per second in the opposite direction.
