Air

Air is a block in Minecraft used to represent unoccupied spaces.

Obtaining
Air cannot be kept in the inventory and can only be destroyed or created by the placement or removal of other blocks respectively.

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

Usage


Air, like any non-solid blocks, are spaces the player and other mobs are allowed to move within without suffocating.

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.
