Röhrchen [rˈøːɾçən] provides pipes which can transfer items in large quantities from one place to another.
As of right now, it provides Glass Pipes. These can only be placed in a clear way where always only one input and one output are possible. Each input begins with a Pump, which also determines the rate of the transferred items. The output of a pipe can be either kept empty or directly lead into a container like a Chest or a Barrel.
