Input: 2 ml human saliva provided by a Class-D test subject 
Result: Substance later proven to be human saliva fell on the test 
site for 8 minutes. Non-grass plants moved to the test site grew 
small (2-5cm) spherical sacs along stems or thin branches. When 
the plant was approached by the test subject, the sacs violently 
expelled a saliva-like liquid toward the subject. Subject reported no 
illness or injury. Augmented plants began to die within 3 days. 


Input: 10 ml 99.999% isotopically pure heavy water (D2O) 

Result: Standard precipitation pattern (27 minutes of drizzle). Mass 
spectrometry of samples revealed a deuterium abundance of ~154 
ppm, which is standard for natural water. 


Input: 5 ml elemental mercury 
Result: Sample began to be absorbed, but was then re-exuded.

SCP-108: Extradimensional Nasal Cavity 


Item #: SCP-108 
Object Class: Safe 


Special Containment Procedures: SCP-108 is contained entirely 
by Subject 108-1. Subject 108-1 should be contained in a standard 
containment cell measuring 3 m x 3 m furnished with whatever items 
are requested unless said items compromise security. Subject 108-1 
is permitted to leave the room, wander freely, and eat in the main 
canteen. Medical examination to be performed on Subject-108-1 
daily; filters to be changed as necessary. 


Description: SCP-108 is accessible through the nostrils of 
Subject-108-1. Subject is an African-American female, 51 years old 
(see Addendum 108-1), who was previously employed as a cashier 
at , a small town hardware store in , Kentucky. 
Since - - ,SCP-108 has been housed at Site-17. 


Endoscopic examination of SCP-108 reveals that the area 
accessible via the subject's nostrils is not the human nasal cavity, 
but rather a bunker system of Nazi German construction dedicated 
to the production and maintenance of WW2-era Messerschmitt Me 
262 fighters. Exploration via robotic endoscope reveals that the 
bunker system has internal dimensions of approximately 2 km x 

4 km, with the long axis parallel to the main entrance/exit portal. 
While the exploration is by no means complete, SCP-108 is believed 
to contain hundreds of airframes under construction on its assembly 
line as well as three completed aircraft. There is also a large 
quantity of human remains in the complex, particularly concentrated 
around the entry/exit portal, with the corpses of Nazi officials, 
military personnel, Hitler Youth, and civilians (possibly Ukrainian 
slave workers) in an advanced state of decay. Evidence of a firefight 
near the entry/exit portal supports the hypothesis that the German 
military personnel were swarmed by the civilians and were killed in 
the ensuing struggle. Some corpses show signs of cannibalism. 


Robotic endoscopic exploration continues, and high discharge LED 
lighting (assembled piecemeal using the "ship in a bottle" technique) 
has been deployed. Endoscopic examination of the interior of 
SCP-108 reveals a large "hangar door" area with a kind of double 
airlock with blast doors large enough to admit two fully assembled 
fighters. A production line exists which would allow damaged 
fighters and deliveries to enter on one side of the hangar door, and 
finished fighters to exit on the other side. Turning the endoscope 
head 180 degrees reveals the open doorway as an area of total 
blackness with two nostril-shaped penetrations in it. One nostril- 
shaped penetration is connected to whichever nostril is admitting the 
endoscope, and the other is connected to the interior of a human 
nasal cavity. DNA testing reveals the nasal cavity belongs to the 
subject. The black area is impenetrable and absorbs all wavelengths 
of light that the endoscope can carry. The black area is elastic and 
yielding when probed. 


Apparently the portal system is a unique three-way arrangement. If 
the outside world is designated A, the interior of the Me 262 factory 
is B and the subject's nasal cavity is C, then traffic is as follows: 


« Anything (including gasses and light) going from A end up in 
B. 

¢ Items going from B end up in C. 

¢ Items going from C end up in A. 


Presumably in 1944 it was intended that C and A were to be the 
interior and exterior of a double hangar at Tempelhof based on the 
architecture of the hangar doors. 


Addendum 108-1: Subject claims that she was training to perform 
the "Human Blockhead" magic trick in preparation for being a clown 
at a children's birthday party. After hammering a 4 cm long 
galvanized-iron nail into her nasal cavity, she lost her grip on the 
end and dropped it inside her nose. Immediately she noticed a "god 
awful musty stench" and experienced nausea and disorientation. 
Blowing her nose had no discernible effect, and left no residue on 
tissues. She was able to breathe normally through her nose. After 
about three days subject "got used to the ‘hell's asshole smell" and 
performed at the children's party to the delight of her nephew. 


Approximately a week later, after ignoring numerous complaints 
about the smell of her breath, subject was diagnosed with 
pneumonia and placed on a course of Roxithromycin. Pneumonia 
responded to antibiotics, but recurred a week later. Her general 
practitioner also noted that nasal examination with an otoscope 
showed simply blackness, rather than the inside of the nose. After 
admission to hospital with chronic pneumonia, examination with a 

1 m fiber-optic endoscope allowed the endoscope to be threaded in 
almost the full meter. The attending ENT noted that he appeared to 
be seeing a "Nazi Eagle badge" through the endoscope. Specialist 
examination notes were kept in a digital patient management system 
and intercepted by the Foundation in a routine - - = = 
sweep. 


The subject was recovered without incident by Task Force Epsilon-9 
disguised as High Risk Warrant Team officers in a pre-dawn raid in 
June of 19 . By the end of the cleanup operation the GP, ENT, 11 
hospital personnel and two civilians were terminated. The subject 
was examined by Foundation staff and provided her with air-filtration 
units which could be passed through her nostrils piecemeal and 
assembled like a "ship in a bottle". The filtration filling must be 
removed on a regular basis when it gets expended (roughly once a 
week) as the subject is essentially inhaling the atmosphere of a 
formerly-sealed Nazi mass war grave. 


Although initially hostile toward the Foundation, the subject has 
responded well to enhanced psychological conditioning protocols 
and now accepts her situation. A plan has been proposed in line 
with the "Backing up" of all critical Foundation data at Site-62 in 
SCP-108: Data could be written on to MicroSD cards or similar 
compact non-volatile media and inserted into the subject's nostrils, 
provided some way to house the subject in a safe location is 
assured in the event of an XK-class scenario. Research continues to 
find a way to move the entrance of the dimensional portal from the 
subject's nostrils to another location and to discover the physical 
location of the bunker to determine if alternative access is possible. 


The original galvanized-iron nail has yet to be found.

SCP-109: Infinite Canteen 


SCP-109 


Item #: SCP-109 
Object Class: Euclid (See Addendum 109-1) 


Special Containment Procedures: SCP-109 is currently located in 
Non-Critical Storage Unit 7 and requires no active monitoring. It 
should not be removed from the unit except to be transported to a 
research facility, and then only by personnel with Level 3 security 
clearance or higher. When replacing SCP-109, personnel should 
ensure that it is firmly closed and that it is placed on the molded 
pedestal in the upright position. 


Description: SCP-109 is a standard-issue United States Army 
canteen (circa 1899) made of atin alloy and fitted with a heavy 
cotton cover and a black leather strap. When opened, the item is 
seen to be nearly full of water. A seemingly unlimited amount of 
water can be removed from the container without changing the 
water level or the item's mass, which remains a constant 3.16 kg. 
Probes of the interior of the container reported an estimated volume 
of 2.8 L and a shape consistent with the outside. 


The water in SCP-109 is of a slight blue-gray tint, with 
concentrations of 20 ppm of tin and 170 ppm of other electrolytes. 
The water remains at a constant temperature of 19°C but can be 
heated or cooled when moved to another container. 


Addendum 109-1: Upon the item's delivery to Site 19, it was given 
the object class of Safe. As tests were conducted on the item, 
uncertainty surrounding test results prompted Gen. to 
upgrade the object class to Euclid. 


Addendum 109-2: Recently, a request was filed and granted by Dr. 
for permission to water an okra plant growing in his office with 
SCP-109. Staff should be notified that Dr. uses SCP-109 for 


this purpose for a small time every Friday. 


Addendum 109-3: "/t has come to my attention that new class D 
personnel are often dared to empty the bottle. Guards are reminded 
that they are to discourage such activity, and inform them that 
SCP-109 is bottomless. Chanting 'Chug! repeatedly is considered 
unprofessional." — Dr. Klein 


Additional Information: Due to the range of tests conducted on 
SCP-109, this section has been provided to present test results in 
chronological order. Dates have been withheld for confidentiality. 


TEST 1: Subjects imbibed water from SCP-109, reported 
that it was very refreshing and, despite the metal 
content, very tasty. Urine samples from subjects were 
normal. 


TEST 2: Follow-up test to TEST 1 had subjects 
dehydrate themselves for 1 full day before imbibing 
water from SCP-109. Test remains unfinished as 
subjects were unable to provide urine samples. 


TEST 3: Subject bathed in water from SCP-109. Subject 
reported increased energy and a much improved 
complexion following the bath. 


TEST 4: Streptococcus bacteria cultured in water from 
SCP-109 thrived and multiplied quickly. Water from 
SCP-109 administered to subject suffering from 
streptococcal infection killed nearly all bacteria and 
produced a full recovery within 24 hours. 


TEST 5: Blood substitute created using water from 
SCP-109, given in transfusion to pedestrian hit by a 
drunk driver. Subject showed no malign symptoms from 
the transfusion and made a full recovery. Subject's 
physical therapy concluded six weeks early. 


TEST 6: Water from SCP-109 administered to various 
plant organisms, all of which remained very healthy and 
showed no malign symptoms. 


One proposition for a test which has been discussed for 
some time has been one involving a combination of 
SCP-109 and SCP-402. Due to the risk of losing one or 
both items or creating a hazardous situation, this test has 
never been conducted.

SCP-110: Subterranean City 


Item #: SCP-110 
Object Class: Euclid 


Special Containment Procedures: The entrance to SCP-110 is to 
remain closed off at all times unless otherwise permitted by O5- . 
The land covering SCP-110 (roughly 6 square kilometers) is to be 
developed into a suburban area that will not attract the attention of 
the general public. Any movement that SCP-110 might make is to be 
explained as "minute seismic activity". Further complaints are to be 
ignored. 


Description: SCP-110 is an entire city that was found buried 0.5 
kilometers underneath a large farm in [DATA EXPUNGED], New 
York. Survey Teams 2 and 3 concluded that the amount of surface 
area that the city is buried under covers approximately six (6) square 
kilometers. Numerous items of high interest have been discovered 
within SCP-110, and will henceforth be labeled as SCP-110-xx. 


Known History of SCP-110 


11/08/19 : A large earthquake occurs in rural New York, far from 
any city centers. The only casualties were a man and his dog, so no 
significant media attention was given to the event. 


15/05/19 : Minor earthquakes continue to occur in SCP-110's 
general area. The US Federal Government dispatches a team of 
geologists to the site to determine the cause. Results come back 
inconclusive. 


16/05/19 : SCP-Excavation Team 03 is ordered to investigate the 
site. Upon arrival, the team is greeted by SCP-110-01, who is then 
detained and moved to [DATA EXPUNGED}] for further questioning. 


24/05/19 :\Information gained from SCP-110-01 and SCP- reveal 


that there has been a large temporal disturbance in the area of 
SCP-110 that has been causing earthquakes due to displacement of 
soil and rock. Another SCP-Excavation Team is sent to the site. 


09/02/20 : After many months of work, SCP-Excavation Teams 04 
and 05 are only able to reveal the strong, impenetrable, concrete- 
like shell of SCP-110. Investigation is halted until further information 
becomes available. 


25/07/20 : Due to the recent decoding and decryption of the files 
contained on SCP-_ , schematics of SCP-110 have become 
available. Excavation teams 04 and 05 are sent back on-site to 
locate the primary entrance of SCP-110. 


04/08/20 : The entrance to SCP-110 has been discovered, and the 
excavation teams are immediately met with what can only be 
described as a "foul odor". SCP-110 had been an active Class-4 
city, but due to a temporal accident, its core services were heavily 
damaged and the entire city was displaced. Work begins to cover up 
the existence of SCP-110, its excavation, and the thousands of dead 
civilians inside. 


Layout of SCP-110: 


The general layout of SCP-110 is essentially a series of concentric 
rings connected by tram, train, and other transportation lines. 
Surveyors have determined that SCP-110 has numerous sections 
and levels to it, all with specific functions, which shall be described 
in greater detail here: 


Core Services: The numerous maps found posted in what were high 
traffic areas of SCP-110 labeled a central 'column' of assorted 
utilities as ‘Core Services’. Upon exploration, which was limited due 
to heavy security restrictions, SCP-Exploration Team 01 discovered 
a myriad of technologies that kept the underground city self- 
sufficient. Among these technologies were a series of matter 
reconstitution chambers, a combination reactor that provided energy 
from both nuclear fusion and geothermal sources, an elaborate 
water recycling system, and a large waste reconstitution area. The 
core is surrounded by numerous elevators and emergency 
stairwells. Numerous areas of the Core have been assigned to 


certain personnel for research. 


Atrium Colossi: This large, open, domed area surrounds the Core, 
and apparently once held vegetation. The dome itself was a massive 
display (its composition undetermined), which was used solely to 
depict a sky as an indication of time of day. Numerous tram-lines 
span at least 3 stories of the atrium, all leading to and from the Core. 
Personnel have described them as looking like "spokes in a wheel". 
Upon discovery, the death toll per area was highest in this area, 
suggesting that it was a high-traffic part of the city. 


Commercial Ring: A ring of what used to be small, independently 
owned shops and chains surrounds the Atrium Colossi. It is 
unknown whether or not commercial products were manufactured 
within the city, however due to the immense size of the Core itself, 
and the city's apparent self-reliance, it is highly likely that the Core 
possesses a manufacturing area. 


Habitation Ring A: The styles of living spaces found in this area 
suggest that its inhabitants were the wealthiest of the city. 
Numerous documents found throughout the city seem to confirm this 
assumption as well. 


Habitation Ring B: This entire ring was inhabited by the middle-class 
citizens of SCP-110. The area is still being searched for items of 
interest. To date, SCPs have been recovered from here.
