Underwater Torch

An underwater torch is a non-solid block that emits light underwater.

Breaking
Unlike a normal torch, an underwater torch does not break if water occupies its space.

Like normal torches, an underwater torch breaks instantly and drops itself when broken using anything. The tool does not lose durability when breaking the underwater torch.

Underwater torches are also broken if pushed by a piston.

Crafting
As with any torch, an underwater torch can be crafted with coal or charcoal. The player can also use a torch from the creative menu.

Usage
An underwater torch can be used exactly like a normal torch, only it can be underwater.
 * Underwater torches can be placed on the top or the sides of most solid blocks, although some require (see placement for exceptions). Being non-solid, an underwater torch has no collision box.
 * Gravity-affected blocks like sand and gravel do not fall if the block below them has an underwater torch on it, and they break if they fall onto an underwater torch.

Placement
In general, underwater torches can be placed only on solid, opaque, and full blocks; exceptions are listed below.

Light
Underwater torches emit a light level of 14. Underwater torches also melt snow layers and ice within 2 blocks (taxicab distance).
