In the Bedrock Edition, it may be obtained as an item via inventory editing.[Bedrock Edition only]
When generating the world, caves, ravines and underwater ruins will be created below the water surface. When lava is generated in the former two, some lava will be converted to obsidian, and some to magma blocks which will generate bubble columns. All bubble columns will generate bubble column blocks until the bubble column is on the surface of the water space it’s in or a solid block is in the way of the would-be taller bubble column.
A player or any other air-breathing mob can enter a bubble column to replenish their air supply. Water-breathing mobs will avoid bubble columns and will 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 and Legacy Console editions 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. Bubble columns can also be created in downwards flowing water[Bedrock Edition only], however this will cause all water to be converted to water source blocks. Bubble columns will not propagate through waterlogged blocks.
Whirlpool bubble columns can be seen by air bubbles wandering downwards. They drag entities downwards. When a magma block is placed underwater, a whirlpool bubble column is generated. When riding a boat over a whirlpool it will begin to shake, and will sink if kept above the whirlpool for too long.
Upward bubble columns can be seen as vertically rising air bubbles. When soul sand is placed under source water blocks, an upward bubble column is generated. An upward bubble column accelerates entities upwards. The longer an object rises through the bubble column, the faster it will travel. 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 will cause entities to bounce upwards repeatedly by about 1 block.
In Bedrock Edition, bubble columns uses the following data values:
|0||The bubble column is a whirlpool.|
|1||The bubble column is upwards.|
|Name||Default value||Allowed values||Description|
|drag||Determines whether the bubble column is upwards or whirlpool.|
