Invisible Bedrock

Invisible Bedrock is an invisible, indestructible block which surrounds all worlds. When placed, it is possible to see through walls, but cannot be destroyed. When held, the item texture looks like that of a cobblestone/stone - like item. Ladders can be placed on it, allowing you to climb over the invisible wall surrounding the maps. (as of 0.6.1 this is not possible but can be put on using world editors.) If you go high enough in Creative mode, it can be walked on. You will see through the blocks lined up against the Invisible Bedrock. Although it is transparent, invisible bedrock does leave a shadow, which can give away secret bridges or defences.

If you shoot an arrow into Invisible Bedrock it will continue until it has reached the level of visible Bedrock, and will turn black, like it has a block on top of it blocking the light. There is a glitch where putting blocks at max height next to Invisible Bedrock and walking into it will cause you to clip through the Invisible Bedrock and appear to float on nothing. You are in fact walking on the top layers of this block. At this point, the player will be invisible in third person, when an arrow is shot it will turn black, and when items are thrown they will disappear instantly, and mobs at these layers are also invisible, so it is advised not to spawn hostile mobs up there. Looking at max height blocks from standing on this will make parts of the block invisible.

In the lite version, hitting this block will give off rock particles, even though this block is meant to be invisible. When hacked into the game however, it has a gray grass pattern on it; the same color as the particles it gives off.

Placing a torch on a block one block's space worth away from the invisible bedrock will have the torch appear on the invisible bedrock. This block is similar to the end of the world limits in the Xbox 360 edition as the Player cannot go any further out the map. As of update 0.9.0, any infinite or superflat worlds have the invisible bedrock barrier removed, also meaning that invisible bedrock is no longer in Pocket Edition in infinite worlds.

Trivia

 * Snowballs and Eggs can pass through Invisible Bedrock.
 * If you spawn animals from Spawn Eggs in the Invisible Bedrock it will suffocate.
