Water

Water is a liquid that can put out Fire and Lava. It has different game mechanics from Lava - it flows faster and does not make the player take damage directly, although players can drown in Water.

Water spawns naturally in the form of lakes, pools, oceans, waterfalls, and rivers.

Usage
Water can be used to make Farmland become hydrated and for fishing. It can also be used to destroy non-solid blocks like Torches and Tall Grass. Water can extinguish Fire and Lava.

Infinite Water Source
Arranging water source blocks in a 2x2 square or a 1x3 rectangle creates an infinite water source, through which water can be used infinite times to fill Buckets and Empty Bottles. Natural infinite Water sources can be found inside Villages and Desert Wells.

Danger
The player has 10 air bubbles when underwater, which slowly deplete when they stay in water too long. Once they fully deplete, the player starts to take damage, and may drown, but this can be minimized by equipping a Respiration Enchanted Helmet. This can occur commonly in large stretches of water.
