Special Containment Procedures: SCP-1056 is to be kept in a 
50x50x50 cm 10-digit combination safe with biometric confirmation 
when not being used for testing. Only personnel involved in 
SCP-1056 research and testing may have access to the object. All 
tests require prior authorization by the Site Director or and by 
research staff with Level 3 clearance or higher. Tests on living 
subjects must be conducted in a secure testing facility meeting Level 
2 containment guidelines to prevent modified subjects from 
escaping. All objects altered by SCP-1056 must be kept in Class E 
ablative storage for 48 hours after transformation. The creation of 
any object or organism over 200 kg must be approved by the Site 
Director. 


Description: SCP-1056 superficially resembles a burnished chrome 
kitchen timer with numbers ranging from 0.25 to 4.00 and an 
activation button on the right-hand side. A 1x1.25 meter wire mesh 
platform is connected to the device by a 3 meter insulated 
molybdenum carbide wire coated with molybdenum disulfide and an 
unidentified organometallic complex; the mesh is capable of folding 
into a 27 x 35 cm square. When the device is set to a number and 
the side button is pushed, any objects in direct contact with the wire 
mesh platform will scale up or down in size by a factor 
corresponding to the number setting. 


The device was recovered by SCP personnel following reports of 
unusual behavior among students at High Schoolin  , PA. 
School officials began an investigation when teachers reported that 
a number of students were behaving unusually. Specifically, the 
students displayed significantly impaired language skills, abnormally 
poor attention span, long-term memory, and impulse control. 
Medical examination of the students revealed the presence of 


numerous vascular and nervous system abnormalities. Foundation 
personnel recovered the device at the home of one of the students, 
who had presumably been using it for recreational purposes. The 
only indicator of the manufacture or distribution of the device is a 
4x1 cm imprint on the bottom of the device reading "THE 
FACTORY”. All electronic components are of generic make. 


The manner in which objects are resized appears to follow a set of 
rules that varies depending upon the complexity and function of the 
object. Simple inanimate objects such as minerals, metals, and 
plastics scale up or down to precisely (to four significant figures) the 
scale indicated without any regard to molecular or microscopic 
scale. For instance, a 5.00 cm stainless steel cube on the 3.00 
setting scaled up to a 15.01 cm cube that was indistinguishable in 
molecular composition from the original cube but that differed ona 
microstructural level; average grain size on the two cubes was 
identical, and individual grains on the small cube did not scale up to 
the large cube. 


SCP-1056 appears to scale complex devices and biological 
organisms with some attempt to maintain the functional properties of 
the object or organism. For instance, the microprocessors of 
electronic devices are often modified if the altered scale would result 
in nonfunctional transistor gates, insufficient power, or excessive 
heat build-up. Devices that have been scaled down often have a 
reduced number of transistors and may demonstrate floating point 
errors. While all but the most complex mechanical objects scale 
relatively well, electronics are often rendered nonfunctional when 
scaled below 0.50 and above 3.00 of their original scale. 


Living organisms that have been resized by SCP-1056 retain their 
basic anatomical structure but often experience significant 
reorganization of the circulatory, pulmonary, and especially nervous 
system. Cell size and composition remain identical to that seen in 
the original organism, but the number of cells increases or 
decreases proportionally to the change in volume. The only 
exception to this observation is the nervous system, where the 
average neuron may increase or decrease up to 25% in linear size 
(thus, potentially becoming slightly under half or over twice the 
original volume) with negligible effects on function. Interestingly, 


SCP-1056 appears to “split the difference” with single-celled 
organisms, slightly altering the average cell size and also altering 
the overall cell population. 


Humans can be resized by SCP-1056 as low as 0.50 and as high as 
1.75 with minimal change in function. Shrinking humans often 
results in increased gyrencephaly (folding) of the cerebral cortex, a 
reduction in average neuron volume, and a decrease in white 
matter. This appears to preserve cognitive function down to 0.50. 
Attempts to scale humans below 0.50 results in a substantial 
decrease in cognitive function, language comprehension, and short- 
and long-term memory, indicating that this is the minimal size 
required for human-like intelligence in a mammalian brain. Humans 
scaled above 1.25 demonstrate slowed reaction speeds, a reported 
increase in creativity, and substantial improvements to long-term 
memory. Scaling beyond 1.50 greatly increases the risk of 
cardiovascular disease, stroke, aneurism, and renal failure. The 
scaling of any organism beyond 3.00 is highly discouraged. 


The mechanism by which SCP-1056 institutes these changes in 
scale is currently unknown. High-speed video footage of 
transformations up to 20,000 fps indicate that the transformation is 
nearly instantaneous, as there is no apparent transition between 
forms. 


Interestingly, there are no apparent effects of atmospheric 
displacement, even when the volume created or destroyed is very 
large. In a minority (roughly 8%) of cases, an object altered by the 
device experiences a material instability and begins to undergo 
atomic decay within 36 hours of alteration. Living organisms and 
other objects with relatively low metal content have a considerably 
lower (roughly 3%) chance of undergoing decay. This decay 
produces significant heat and energy — approximately 150 
gigajoules per kilogram - around six orders of magnitude less than 
typical matter-antimatter decay but sufficiently high to render 
frequent or high-mass transformations inadvisable. 


Experiment Log SCP-1056 
Experiment Log SCP-1056 


Experiment SCP-1056-1 

Object: T|-30Xa scientific calculator. 

Setting: 0.75, 1.33 

Result: Functional 0.75 scale calculator. The calculator 
was successfully returned to a 1.00 scale using the 1.33 
setting. Repeated transformations between the two 
settings does not appear to alter the basic function, 
appearance, or internal composition of the calculator. 


Experiment SCP-1056-2 

Object: T|-30Xa scientific calculator. 

Setting: 0.25, 4.00 

Result: Nonfunctional 0.25 scale calculator. The power 
button of the calculator turns it on, but it is incapable of 
performing accurate calculations. Most calculations 
result in either incorrect results or an ERR signal. Return 
of the calculator to normal scale using the 4.00 setting 
did not return function to the device. Internal analysis 
indicates loss of fine details, including transistor number 
and LCD resolution, in the device. 


Experiment SCP-1056-3 

Object: 1 kg bar of 22 carat gold bullion. 

Setting: 4.00 

Result: 64 kg bar of 21 carat gold bullion with minor 
molybdenum impurities. 


Experiment SCP-1056-4 

Object: 35 one ounce (28.35 gram) “Silver Eagle” bullion 
coins. 

Setting: 2.00 

Result: 99 bullion coins weighing 80.18 grams apiece. 
The increase in total mass seems to be evenly split 
between increasing the average size of the coins and 
increasing the total number of coins. 40.25 hours after 
the transformation, the coins began to emit 
electromagnetic radiation, eventually emitting high levels 
of heat and ionizing radiation. The mass of silver was 
stored in the high explosives test chamber at Site 40 until 
the mass had completely dispersed 20 hours later. This 


resulted in extensive damage to the test chamber and 
the treatment of four researchers for radiation poisoning. 
Researcher’s Note: /f we can identify the objects that 
will do this prior to their decay or reliably induce decay in 
a Class of objects, then items altered by this SCP could 
be used for power or even weaponized. There does not 
appear to be any underlying constant to what items are 
susceptible to or what SCP-1056 process initiates this 
decay. —Dr. Bimston 


Experiment SCP-1056-5 

Object: Human subject D-3202, a 52 year-old male, 

175 cm tall and weighing 90.3 kg. 

Setting: 2.00 

Result: The subject scaled up approximately twofold to 
341 cm tall and weighing 719.6 kg. Mental and 
physiological functions appear normal. Reaction times 
are slightly lower than normal and required caloric intake 
is only 50% of what would be expected, given the nearly 
eightfold increase in mass. The subject performs 
extremely well on long-term memory tests, perhaps 
owing to increased brain mass. Resting heart rate is 45 
bpm and systolic pressure is 165 mm Hg (versus 132 
before the transformation). Six days after the 
transformation, the subject experienced vascular 
irregularities leading to moderate swelling in the distal 
limbs, followed by intermittent bouts of confusion, 
spotted vision, blurred vision, and tinnitus. The subject 
died from respiratory arrest caused by a massive 
brainstem aneurysm 22 days after the transformation. 
Researcher’s Note: The subject’s symptoms suggest 
the rapid onset of complications consistent with cases of 
extreme acromegaly (gigantism). Our projections 
indicate that most humans would tolerate scales of up to 
1.33 or slightly above relatively well. —Dr. Kearns 


Experiment SCP-1056-6 

Object: Human subject D-3315, a 36 year-old female, 
163 cm tall and weighing 55.0 kg. 

Setting: 0.50 


Result: The subject scaled down approximately twofold 
to 81 cm tall and weighing 7.0 kg. Mental and 
physiological functions appear normal. There was no 
significant difference in tests of general intelligence, 
short- and long-term memory, and spatial reasoning 
administered before and after the transformation. MRI 
scans indicate increased folding in the cerebral cortex 
and an overall decrease in white matter. Resting heart 
rate is 98 bom and systolic pressure is 88 mm Hg 
(versus 115 before the transformation). The subject’s 
cardiovascular system was slightly simplified in a manner 
similar to that seen in smaller primates. Twenty-eight 
days after the transformation, no obvious health or 
behavioral anomalies were observed and the subject 
was returned to her original size. 


Experiment SCP-1056-7 

Object: Human subject D-3315 from experiment 
SCP-1056-6, a 36-year old female, 81 cm tall and 
weighing 7.1 kg. 

Setting: 2.00 

Result: The subject scaled back up to her original size of 
163 cm tall with a weight of 55.7 kg. Mental and 
physiological functions appear normal. Cognitive tests 
indicate a slight but significant improvement in short- and 
long-term memory and a slight decrease in reaction time. 
It is hypothesized that these cognitive irregularities could 
compound or change with repeated use of the device. 
The cardiovascular system appears modified from the 
shrunken version to support the larger body but is not 
identical to the original vascular pattern, indicating that 
the device “improvises” solutions to physiological 
problems anew with each transformation rather than 
reverting to old forms. 


Experiment SCP-1056-8 

Object: Bacterial culture of species E. coli in LB medium 
ona13cm petri dish. 

Setting: 4.00 

Result: The Petri dish scaled up to 52 cm and the 


bacterial colonies increased in volume roughly sixty- 
fourfold while maintaining their original morphology. 
Microscopic analysis of the colonies reveals that the 
average size of the bacteria had increased by a factor of 
2.2 to 7 microns in length with the remaining increase in 
mass owing to an increased number of bacterial cells. 
Samples cultured from these colonies maintain an 
increased size, generally stabilizing at 6 microns in 
length after 20 replication cycles. PCR analysis reveals 
several point mutations in the bacterial genome, such as 
in the rodZ gene, leading to the bacterium’s generally 
increased size. 

Researcher’s Note: Genetic tests indicate that 
SCP-1056 restructures organisms on both a 
physiological and genetic level. This represents a degree 
of abstract sophistication inconsistent with the simple 
digital and mechanical workings observed within the 
device. —Dr. Kearns 


Experiment SCP-1056-9 

Object: SCP-1056 

Setting: 2.00 

Result: [DATA EXPUNGED] 

Site Director’s Note: From now on, all experiments on 
this device must be approved by the senior investigator 
and then submitted to me. The responsible parties have 
been officially disciplined and removed from this project. 
We’re lucky that the effects weren’t much, much worse. 
What would have happened if the entire universe had 
doubled in size? -

SCP-1057: Absence of Shark 


Item #: SCP-1057 
Object Class: Safe 


Special Containment Procedures: SCP-1057 is kept ina 
reinforced glass containment tank 4 meters tall, 15 meters long, and 
9 meters wide, filled with water which has been treated to replicate a 
temperate ocean environment (see document 1057-H-22 for 
specifications). Vegetation in SCP-1057's habitat is to be maintained 
twice a week (see document 1057-H-19 for specifications). It is 
forbidden to enter SCP-1057's tank for 30 minutes before and after 
feedings. 


SCP-1057 is to be fed five (5) kg of raw meat and fish, three (3) 
times a day. Once every four (4) days, this meat and fish is to be 
injected with non-toxic fluorescent dyes (see document 1057-G-4 for 
specifications). The tank is to be lit with ultraviolet lamps. 


Description: SCP-1057 is an animate empty space, five (5) meters 
long, in the shape of an adult tiger shark (Galeocerdo cuvier). |t 
does not appear to have any mass; however, it displaces water by 
an unknown mechanism. SCP-1057's refractive index is 
approximately that of air, which makes it partially visible when 
immersed in salt water; as well, its "anti-shadow" is discernible 
under bright light. Experiments involving the insertion of inanimate 
objects into SCP-1057's "body" have revealed that there is nothing 
there; however, further experiments along these lines are 
contraindicated, as this triggers extremely aggressive behavior on 
the part of SCP-1057. 


SCP-1057's behavior has been assessed by Foundation 
ichthyologists as being within normal parameters for an adult tiger 
shark. Any food consumed by SCP-1057 disappears, with the 
exception of the non-digestible fluorescent dyes which are regularly 
added to SCP-1057's food to facilitate monitoring its behavior. 


These dyes persist within SCP-1057 for five to nine days, and 
outline a digestive and circulatory system; several hypotheses to 
explain how this is possible when there is manifestly no actual shark 
present have been suggested, tested, and disproved (see archive 
1057-N4). 


Acquisition log: SCP-1057 was captured in the Public 
Swimming Pool, in [REDACTED], where it killed two swimmers and 
mutilated a lifeguard; five people were killed in the ensuing panic. 
Foundation personnel embedded in the local hospital reported the 
incident; retrieval agents arrived on the scene and SCP-1057 was 
eventually taken into custody. During forensic examination of the 
swimming pool premises, Document 1057-K24 was discovered on 
the staff bulletin board; although Document 1057-K24 is 
handwritten, no fingerprints were found on it. 


Document 1057-K24: 


Panic means that the idea of a shark can be more 
dangerous than an actual shark. 


It can even be more dangerous than no shark at all. 
Are we cool yet?
