Description: SCP-170 appears to be a standard tube of superglue, 
in a yellow tube 13 cm long. There is no manufacturer information or 
any other text on the outside of the container, apart from the word 
‘'SUPERGLUE printed in bold letters on the front. 


Whenever any amount of the substance is applied to solid material, 
and that solid is put in contact with any surface, both objects lose 
molecular cohesion in the area surrounding the contact points, 
allowing one to be pushed through the other. The effect lasts only 
moments, however. Within a third of a second of the two surfaces 
making contact, the ability of each to pass through the other is 
nullified, leaving both permanently bonded together. 


SCP-170 was seized in a raid on an illegal laboratory in , ,in 
19 . The unusual properties of SCP-170 were unknown until a 
standard test on all seized materials was performed on it. A 
laboratory technician used a pipette to extract a small amount of 
SCP-170 for analysis. Upon attempting to dispense the substance 
onto a slide, the pipette immediately passed straight through the 
slide, which was on a mount. Further tests were run upon the 
pipette/slide, and it was discovered that they were bonded on the 
molecular level. Upon hearing of this, SCP personnel were 
dispatched to confiscate all seized materials. 


Notable tests 


Test 04: 

Test materials: 1 x heavy duty chain, weights of various sizes. 
Procedure: A small amount of SCP-170 was applied to the last link 
of the chain, which was then bonded to the reinforced ceiling of 
containment area 17f. Weights of various sizes were then hung on 
the chain to determine the structural failing point of the bond. 
Results: After approximately 9 metric tons were suspended, the 
chain finally snapped, but not at the bond point. It snapped at the 9th 
link from the bottom. All links apart from the one embedded in the 
ceiling were tested and showed signs of distortion and stretching. 
However, the bond point in the ceiling showed no sign of weakness 
or separation of chain and ceiling. 


Test 07: 

Test materials: 2 x identical cubes of 24 carat gold (as close to 
100% pure as possible) 

Procedure: Using robotic arms to ensure perfect alignment, cube 1 
(the cube with SCP-170 applied) was pushed completely through 
cube 2, leaving what appeared to be 1 gold cube equal in size to 
either of the original cubes. 

Results: Upon examination of the sole remaining cube, it was found 
to have a density of 38.6 grams per cm3, which is precisely twice the 
density of gold. Even melting the sample did nothing to change this, 
as the resulting liquid gold also had the same density. This implies 
that the substances don't displace each other - every atom is 
accounted for. Analysis of the atoms has proven that they are 
regular gold atoms, implying that they don't undergo nuclear fusion 
to accomplish the increase in density. The atoms are simply packed 
into a smaller space than the laws of physics would seem to allow. 


In light of this experiment, Dr. has requested permission to use 
SCP-170 to ‘glue’ two pieces of uranium together to make a more 
fissile sample. Due to the obvious safety concerns this poses, this 
request was denied. 


X-ray of subject's finger bonded to the desk (post amputation). 


The fracture was caused by the subject struggling to free himself. 


Test 12: 

Test materials: 1 x D-class personnel, 1 x wooden desk. 
Procedure: First test using live biological subjects. D-class 
personnel had a small amount of SCP-170 applied to his right index 
finger, and was instructed to "poke the desk". 

Results: Subject's finger sank into the desk up to the first knuckle. 
Despite obvious panic, the subject reported no pain, discomfort or 
sensation below the bond point. However, his finger quickly began 
swelling and turned purple, as his circulatory system continued 
pumping blood to an area that could no longer return it. Finger was 
amputated between the first and second knuckle. 


Test 19: 

Test materials: 1 x Pratt & Whitney F100 jet engine, the reinforced 
ceiling of containment area 19b. 

Procedure: SCP-170 was applied to the jet engine mountings, 
which were quickly pushed 3.2 cm (approximately 1.25 inches) into 
the ceiling of the chamber. After connecting an appropriate fuel 
supply and control system, the jet engine was fired. 

Results: The engine was run continuously at high speed for 40 
minutes, while cameras monitored the join point for any signs of 
stress. While small cracks appeared in the concrete around the join 
point, there were no indications of any possible structural failures or 
separation of the two materials, even under a force of 120,000 
newtons.

SCP-171: Collective Brain Foam 


Item #: SCP-171 
Object Class: Euclid 


Special Containment Procedures: A 4500-liter pool of sea water 
located at Bio-Research Area-12 is the current research location of 
SCP-171. Though not immediately dangerous, minimal physical 
contact between secretions of SCP-171 and its hosts are to be 
observed. All communications between hosts and researchers are to 
be recorded and transcribed. Human hosts are to be fed a vegan 
diet of their choosing. Other animal hosts are to be fed 
appropriately. Fresh sea water is to be cycled into its tank regularly. 


Description: Originally, SCP-171 was thought to be a colony of 
microscopic organisms similar to SCP-968 or SCP-165, but further 
investigations revealed SCP-171 to be a single entity spanning 300 
square meters when first encountered. SCP-171 is a web-like matrix 
of small, fine tendrils of neurons, mucous glands, and muscle fibers 
suspended in a frothy foam of its own creation. It is not capable of 
self-locomotion and does not actively attack or feed on other living 
organisms; rather, it attempts to form a symbiotic relationship with all 
organisms it comes into contact with. 


Flagella of the muscle surrounding the neural fibers work mucus, 
sea Salt, water, and other secretions into bubbles, forming a large 
foam support. Any creature that spends a significant amount of time 
in contact with the matrix of SCP-171 risks becoming integrated into 
a collective consciousness sustained by it. People who become 
covered in SCP-171 foam describe a "tingly" or "tickly" sensation 
experienced, which researchers have observed as threads of 
SCP-171 tunneling through the skin to directly integrate into the 
subject's nervous system. In time, the simple motor neurons of 
subjects are expanded into an elaborate, two-way positive 
communication nexus, allowing the brains of hosts to communicate 
with each other and the entity of SCP-171. Over time, the 


individuality of subjects are incorporated into and shared with others 
of the SCP-171 matrix, resulting in a collective consciousness in 
which individual personalities are non-existent. 


There are currently 19 human subjects host to SCP-171 (11 civilian, 
8 class D personnel). Subjects are capable of traversing the foam 
without losing conscious contact with the collective as 
neuroreceptors on the subject's skin form to allow chemical 
communication between the subject and SCP-171 much in the same 
way terminal axons communicate with dendrites in the brain. These 
receptors on the skin look like small white to clear moles, slightly 
raised and very sensitive to touch. Some subjects disappear into the 
foam of SCP-171 and are not seen again for several months. It is 
unknown how they survive without fresh water or sustenance. 


Other hosts include: 2 Australian porpoises (originally 4), 4 beach 
gulls (3 have been euthanized), 41 fish of various species 
(euthanized for study), 27 beach crabs (euthanized for study), and 1 
canine. Within two hours, most subjects begin forming 
neuroreceptors on the skin and receiving neural contact with 
SCP-171. After three hours, a psychological bond has been 
established between subjects and the collective. After 6 hours, a 
complete integration and dependency on the collective has evolved. 
At this point, removing the subject from contact with SCP-171 
results in manic and violent behavior along with eventual complete 
psychological breakdown of the individual, leading to a vegetative 
state of mind (4 individuals have been lost in this manner). 


When interviewed, all subject hosts speak with the same core 
collective consciousness as if they were parts of a single entity. The 
collective is aware of itself and its composure of diverse individuals, 
and even laments the loss of each individual persona. SCP-171 tells 
researchers that it understands what it is, but not where it came 
from, explaining that its own intelligence and the intelligence of the 
hosts it incorporated were too simple to understand or remember its 
origin. Researchers noted the change in SCP-171's personality after 
integrating Class D personnel and chose not to allow inclusion of 
violent, ill-willed, or malevolent personnel from that point on. 
SCP-171 has expressed that through meditation and understanding, 
it chooses to avoid the consumption of other animals when possible. 


Addendum 171-1 SCP-171 was first encountered by beachgoers 
and surfers on August 12, 2007, along the Australian coastline near 
Yamba, New South Wales. When civilians playing in the foam began 
experiencing abnormal skin conditions, CDC officials contacted SCP 
personnel when they were unable to explain the anomaly. 


Addendum 171-2 Personnel who wish to be voluntarily integrated 
with SCP-171 must first be subject to a complete psychological 
evaluation to ensure sound mental health, with special emphasis on 
possible disconnection from humanity and potential suicidal 
tendencies. They are to be repeatedly warned that such integration 
is permanent, and that no evidence exists to show that SCP-171 in 
any way exhibits a state of 'higher consciousness’, or indeed a 
consciousness significantly different from our own. If subject persists 
in wishing to be integrated, and has been shown to be making the 
decision in a state of sound mind, then they are to be permitted to 
do so.

SCP-172: The Gearman 


Item #: SCP-172 
Object Class: Euclid 


Special Containment Procedures: Any personnel wishing to 
access SCP-172 must receive written approval, and undergo a one- 
hour training session. All interaction with SCP-172 must be 
overseen by at least one class 4 operative, who may end the 
session at their discretion. Any and all records, drawings, or 
correspondence produced by SCP-172 are to be submitted 
immediately to Dr. for review. Reasonable requests made by 
SCP-172 are to be granted after approval by Dr. .SCP-172is 
allowed out of its containment area with approval, as long as it is 
accompanied by an armed class 4 operative. 


Armed personnel are to be stationed at the door of SCP-172. Should 
SCP-172 attempt to escape, it is to first be asked to cease and 
desist, and then led back to its containment area. Containment area 
is to be kept stocked with paper, pencils, and any additional 
components requested by SCP-172. Tables, chairs, and any 
additional furnishings requested by SCP-172 are to be provided 
pending approval by Dr. _ . Upon entering its dormant state, 
SCP-172 should be placed in its transportation box until re-wound. 


Description: SCP-172 appears to be a human being, 34 years of 
age, 185 cm (6 ft 1 in) tall, black hair and mustache, 175.5 kg 

(386 Ib), and of Russian descent. SCP-172's personality is very 
friendly and intelligent, if somewhat dull and repetitive. SCP-172 
prefers dress from the 1860s, and always wears a large, ornate key 
on along necklace. SCP-172 has never identified itself by any 
name, and is not upset by being referred to by its designation 
number. 


Internally, SCP-172 is a staggeringly complex automaton, 
possessing over two million moving parts, and eighteen million 


components at last count. Component parts appear to be made of 
glass, silk, wood, steel, brass, rubber, and several other substances. 
Similarity between this construction and that of SCP-2776 suggest a 
similar creator or creators. SCP-172 also has several “modules” that 
can be installed via a hatch in its chest. These appear to alter 
behavior, soeech, movement, and several parameters based on 
position in the body cavity and module components. SCP-172 has 
46 modules at current count, having built three of these while in 
Foundation custody. Currently, SCP-172 is loaded with the 
"engineer" module. Modules have been identified by SCP-172 as 
"caretaker", "soldier", "medic", "mother", and "king", though this is by 
no means a comprehensive list (refer to Document #1 72-2). Under 
no circumstance are modules to be replaced without O5 level 
authorization. 


SCP-172 is powered via a mainspring, which is wound with the key 
in SCP-172's possession, after inserting it into a hole at the base of 
the neck. SCP-172 can operate for eight hours on a single full “wind- 
up.” SCP-172 appears wholly human when in operation, and is 
capable of all basic human functions. SCP-172 has no need to eat, 
breathe, or sleep, but will perform all these functions if allowed to do 
so. SCP-172 is extremely obedient, and will follow any instructions 
given to it to the best of its ability. 


SCP-172 does not view its existence as strange, and asserts that it 
is human even when shown its internal components. SCP-172 is 
also extremely delicate, and great care must be taken to preserve 
and maintain its function. SCP-172 has also shown a level of 
mechanical skill nothing short of miraculous. SCP-172 is capable of 
analyzing and copying any mechanical device it comes in contact 
with. This was first shown when it became apparent that locks of any 
kind cannot contain SCP-172. It has also made several copies or 
“upgraded” versions of SCP technology, all based on incredibly 
complex clockwork. Most notably, [DATA EXPUNGED]. 


Document #172-4R: Notes on recovery of SCP-172 
SCP-172 was recovered after the Great War, in a chamber below a 


former vacation home of the Czars. Exposed due to stray bombing, 
the chamber and its contents were badly damaged, but SCP-172 


was found intact in an iron crate, along with many “modules” and its 
key. Item was removed by operatives, and “wound-up” inside testing 
facilities. SCP-172 appeared to wake up from a deep sleep, and 
proceeded to greet everyone present in Russian. When Agent 

shouted in surprise, SCP-172 pushed against its chest, and 
repeated its greetings in English. SCP-172, when questioned, stated 
that its last memory was playing with a young boy. The boy left, and 
SCP-172 began to feel “very tired,” so it returned to the box. It has 
no memory of its creation, creator, or name.
