Spout

Spout is a 1-slot storage. If you place some liquid (as items from your inventory) into the Spout, then it will slowly pour this liquid into the world. It's an automated way of pouring the liquids by hand (via the "place blocks" mode of Matter Manipulator), and can be very convenient if you need to pour a lot of it.

You can connect Spout to the Item Transference Device to automatically receive the liquids from somewhere else.

Despite what it tooltip claims, it is NOT a part of Liquid Network and can NOT be connected to it.
