Obsidian Pipe

The Obsidian Pipe will automatically collect items that come into contact with it. Applying power from an engine to the pipe will increase the range of items it can suck to 1 block (distance has been increased to roughly 4 blocks for all engines other than Redstone Engines as of 2.0.1). Redstone Engines suck up one item per pump, while other engines suck multiple items up at a time. Without the engine, the items need to touch the pipe to be sucked in.

The Obsidian Pipe can also extract items out of the inventory of a minecart with a chest. A much less expensive way to make the effective distance of a Obsidian Pipe is to use many water source blocks to make the items flow towards the Obsidian Pipe.

Obsidian Pipe s will not connect to other Obsidian Pipe s. Obsidian Pipes can not be waterproofed.
