Bubble columns cannot be obtained as an item, and can only be placed by a block-placement command such as
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 can enter a bubble column to replenish their air supply. A bubble column is destroyed when moved by a piston. When creating a bubble column, all blocks above must be source blocks. 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.
Whirlpool bubble columns can be seen by air bubbles wandering downwards and it drags entities downwards. When magma block is placed on the bottom, a whirlpool bubble column is generated. When riding a boat over a whirlpool it will begin to shake and finally will sink if kept above the whirlpool for too long.
Upward bubble columns can be seen with vertically rising air bubbles. When soul sand is placed on the bottom, an upward bubble column is generated. An upward bubble column draws entities upwards. The longer an object is rising through the bubble column the faster they will go. When the speed is high enough, the object (or player) will shoot out of the water by about 1 block.
Entities move at a speed of approximately 15 blocks (meters) per second when inside a bubble column. This is 900 blocks per minute. However, the need for bubble columns to be in a water space and due to the fact that bubble columns are vertical, not horizontal makes it a poor mode of transport.
