Underwater TNT

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

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.

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 damage blocks underwater. It can still explode in the air, although it does not work in lava.

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.
