The Sink

The Sink is a part of the Big Empty in the Fallout: New Vegas add-on Old World Blues.

Layout
The Sink is a one floor area consisting of four rooms with a central room containing the Sink Central Intelligence Unit. All the upgradeable sink units can be found here (the Toaster, Light Switch 01, Light Switch 02, Muggy, Biological research station, Blind Diode Jefferson, Sink Auto-Doc, Book Chute and Sink) along with multiple containers in all the rooms. In its entirety the sink contains a workbench, Reloading bench and Electric hot plate as its usable crafting sources; excluding the use of the sinks units. This area leads to The Sink Balcony, The Think Tank and Big MT.

Upgrades
The Sink can be upgraded by finding back-up personality holotapes scattered around the Big Empty. Many appliances are available for reactivation and upgrading, including:

Sink Auto-Doc
The Auto-Doc in the Sink is a far superior model to other Auto-Docs, because of its multiple functions. It is the only object that offers cosmetic surgery to the Courier and offers several, although pricey, implants after finding them in the Big Empty. The Auto-Doc can also heal you fully, including removing all radiation and addictions. It can also restyle your hair, being the only other NPC that can besides Sergio.

Biological research station
The Biological research station is the mojo mac-daddy of all things agricultural. It has the ability to clone any dried plants found in Seed Bags in the Big Empty, and also can process other plant matter into salient green, the green goo that can create most plants when accessed at a campfire or hotplate.

Blind Diode Jefferson
The music-less jukebox in the Sink is the upgrade hub of all things pertaining to the Sonic emitter. After finding holotapes with certain frequencies in the Big Empty, Jefferson can tune any Sonic Emitter Pistol to that frequency giving the pistol different and unique properties.

Book Chute
The Book Chute is a Communist-hating destroyer of knowledge. It plans to destroy all things that resemble knowledge, and all things which might aid in independent thought, such as pencils. After its upgrades it can break down any pre-War book, clean or destroyed, into blank books. It can also break pencils into lead and scrap metal, as well as clipboards into duct tape and scrap metal.

Light Switch 01
Light Switch 01 is found in the room next to the Toaster, and has a more laid back personality than Light Switch 02. It's second upgrade provides the option for lighting that raises Intelligence, Science and Repair skills for 12 hours after exposure.

Light Switch 02
Light Switch 02 is located in the Bedroom area and possesses an expressed hatred towards Light Switch 01 for its professed superiority of larger processors. Its upgrade provides the option for lighting that raises Charisma, Barter, and Speech for 12 hours after exposure.

Muggy
The miniature Securitron has an addiction for all things relating to dishware, cups, and especially mugs. Its second upgrade allows it to create a small supply of energy cells, scrap electronics and other things once every day.

Sink
The actual, water basin-associated Sink in the Sink is a germiphobe that acts as a source of clean water, and after being upgraded, can fill up any empty bottle (Empty Nuka-Cola bottle, Milk bottle, etc.) with water turning it into purified water.

Sink Central Intelligence Unit
The Central Intelligence Unit acts as the hub for all the appliances in the Sink. It can turn on or off the personalities in the area, leaving them to function in a quieter state. It also acts as the snobbish merchant and repairer of goods and sells certain mods for weapons after their holotapes are found. It does restock items like other merchants, although only after 3 days inside the Big Empty.

Toaster
An evil Toaster with aspirations of a second Armageddon which can turn plain Saturnite fists into the Saturnite fist super-heated. It can also rip apart other small appliances, such as Cameras, Irons, Hot plates, and even other Toasters, into their basic components, acting as a source of energy cells and scrap materials for the work bench or reloading bench.

Appearances
The Sink appears only in the Fallout: New Vegas add-on Old World Blues.

Bugs

 * The game may crash upon ending the initial conversation with the Sink Central Intelligence Unit, making it impossible to barter or begin the quest All My Friends Have Off Switches.
 * The Sink Central Intelligence Unit can glitch, making it impossible to exchange items for caps, no matter how many caps are in the Unit's inventory.
 * When one stands next to the Sink near the outside exit and aims and shoots at the locker that is within the room where your spine and heart are held, your shots reappear through the wall next to you (tested with LAER and Elijah's LAER).
 * When entering the Sink, the two white horsenettle plants can be seen falling from the ceiling down through the planter and through the floor over and over. Also, the plants can only be harvested once. The plants may be harvestable again after completing Old World Blues, returning to the Mojave, and then returning to Big MT.
 * The force field on the balcony is not present even at the beginning of the DLC.
 * If you place an item on any of the tables near the bedroom, they will become invisible until moved again or placed back in your inventory and dropped again.
 * In the bedroom, on the right side of the bed, if you drop an item such as a cup, it will roll 'into' the ground and re-emerge in between the workbench and the exit to the observation area.
 * When throwing a Proton Throwing axe or a Proton Inversal Throwing axe anywhere in the Sink, sparks appear out of the wall right behind the workbench.
