Pocket Air
by sem.entjes11
Pocket Air is a Fabric utility that gives players a craftable item for breathing underwater, and it replaces one water block with one air block on each right click.
What it does
A Pocket Air item is crafted from one Magma Block, and the recipe yields a full stack of 64. Holding the item and right-clicking a submerged water block swaps that block for an air block, which gives the player a quick breath without a sponge. The mod suits deep-sea exploration and underwater bases, where a door or a wall can be placed underwater without first draining the area.
The mod is a lightweight utility with a single purpose, and it depends on nothing beyond Fabric. Client and server both need it, so the server and every player must run the mod. Files exist for 1.21.10, 1.21.11, 26.1, 26.1.1, 26.1.2 and 26.2, and the code is covered by All rights reserved, so the mod is not open source.
