Bubble Column

In Minecraft, a bubble column is a non-solid block generated by placing magma blocks or soul sand in water. Bubble columns push or pull entities and items in specific directions. Magma blocks generate whirlpool bubble columns that drag entities downward, while soul sand generates upward bubble columns that push entities upward. Bubble columns provide air replenishment for players and air-breathing mobs at the same speed as exiting the water. However, players still experience slower underwater mining speeds within bubble columns. Water-breathing mobs avoid bubble columns as they suffocate inside. Bubble columns propagate only through water source blocks, stopping at flowing water or waterlogged blocks. Their height is limited only by the water's surface or obstructing blocks. In Java Edition, bubble columns cannot be obtained as an item and can only be placed via block placement commands like `/setblock`. In Bedrock Edition, they can be obtained as an item via inventory editing, add-ons, or bugs. Bubble columns have various applications in Minecraft, naturally generating in underwater ruins or ruined portals, or created by placing magma blocks or soul sand. They are not just decorative elements, but can be used for transportation, building elevators, or even for special purposes like ender pearl stasis chambers. The generation and destruction of bubble columns are influenced by in-game timers and can be detected by redstone components. Differences in movement speed and acquisition methods exist between versions.
