cave_air[upcoming 1.13]
void_air[upcoming 1.13]

Air is the block present in otherwise empty space.

Cave air[upcoming 1.13] is the underground air found in Generated structures, and is generated in caves.

Void air[upcoming 1.13] is used internally for blocks above (>255) and below (<0) the world, and in unloaded chunks.


Air cannot be kept in the inventory and can only be destroyed or created by the placement or removal of other blocks respectively, assuming the block space is not already occupied by water.[upcoming 1.13]

Natural generation[edit]

Most generated structures generate air. Air is also generated in any space not occupied by another block.

Structures above ground generate normal air (with the exception of exposed mesa abandoned mineshafts and surface ponds, which generate cave air[1][2]), and underground structures generate cave air. Void air is used in place of unloaded chunks and above or below the world's buildable area.


Air, shown at left, is represented by blue cubes within structures. Red cubes represent structure void.

Air shares some properties with non-solid blocks, including allowing the player or mob to move within that space without suffocating, and also to catch their breath if they are drowning in water.

Air can be visualized with the use of structure blocks in save mode. With "Show invisible blocks" enabled, air is represented as small blue cubes.


Cave game tech test Air was added, but it wasn't internally a block.
0.31 Air affected liquid blocks that were horizontally adjacent to it. If air was touching the fluid block, there was a 23 chance the fluid block would disappear and make the pool recede and a 13 chance the fluid block would fill the air, making the pool spread.
