Underwater TNT is a block that can be used by the player to initiate a controlled explosion underwater.

Obtaining

Breaking

Underwater TNT can be broken instantly with any tool, or without a tool. However, primed underwater TNT cannot be broken, as it is an entity.

Crafting

Ingredients	[hide]Crafting recipe
Sodium + TNT

Usage

Underwater TNT blocks can be activated the same way as a normal TNT block.

Behavior

Once activated, it explodes like a normal TNT block. However, unlike the traditional TNT block, it can destroy blocks underwater. It can still explode in the air, although it does not work in lava. Underwater TNT has the same delayed detonation rate as normal TNT.

Trivia

• The inclusion of sodium is a reference to elemental sodium's explosive reaction with water. All alkaline metals react with water violently to form hydrogen gas and a hydroxide. The heat generated often ignites the gas.
