 Item number, SCP-074, Object Class, Euclid. Special Containment Procedures. SCP-074 is contained at Site 81. SCP-074 is an active info hazard. No research in evaluating its anomalous properties is to be conducted. All personnel who have previously engaged in research into SCP-074's anomalous properties must never come within 5 km of SCP-074. SCP-074 is contained within a 6 m x 6 m x 3 m reinforced glass chamber, filtered to block all ultraviolet light, and situated within a windowless room, lit by monochromatic safe lights, which serve as secondary containment. A smaller containment chamber would significantly increase the probability of SCP-074 spontaneously breaching primary containment. The containment chamber is to be surrounded with scaffolds bearing sheets of live, cultured human skin, held parallel to the surfaces of the containment chamber, and arranged overlapping each other such that lateral coverage is at least 95%. Skin sheets must be a minimum of 3 mm thick and warm to 37°C and must be grown from samples provided by D-Class personnel with no less than a middle school education and no more than a high school education. All skin sheets are to be examined on a daily basis for instances of SCP-074-1. All instances of SCP-074-1 are to be excised and incinerated. SCP-074 is to be fed 75 g of fresh shredded apple leaves, genus malus, bark, and fruit, hydroponically grown to ensure lack of pollutants in foreign organisms, once a day via a mechanical dispenser. In the event of a spontaneous containment breach, personnel can coerce SCP-074 into returning to its containment by first occupying each of its four sets of jaws with an entire raw apple, then physically pushing SCP-074 in the desired direction, gently tapping its compound eyes with an open palm, or spraying its front pair of antennae with a 0.5% solution of methanoic acid. Description. SCP-074 is an anomalous organism which uses various quantum properties at a macroscopic scale, and in other ways modifies the standard laws of physics within its immediate vicinity. The specific nature of these modifications appears to be linked to the extent to which humans in SCP-074's vicinity are aware of the precise details of the physical laws which SCP-074 modifies. Such that, research to determine whether SCP-074 has a given property or capability results in SCP-074 developing or manifesting that property or capability. Archive 074-317e, a full list of the anomalous physical phenomena known to be, or to have been, associated with SCP-074, is available to personnel level 3 or higher. Personnel who access this document will be disqualified from working with SCP-074, or for any other reason coming within 5 kilometers of Site-81. SCP-074 has repeatedly manifested the ability to spontaneously materialize at locations as much as 3 meters outside its primary containment. This is believed to be, or to be analogous to, quantum tunneling. Foundation entomologists have tentatively identified SCP-074 as belonging to the order isopoda, commonly known as a woodlouse. Its inertial mass is approximately 1700 kilograms, but its gravitational mass is approximately 375 grams. Its volume has been estimated at 1.7 cubic meters, approximately the size of a compact car. SCP-074 is female, although it lacks the typical isopod marsupium, or brood pouch in which eggs are incubated, and parthenogenetic. Periodically, approximately 1.3 times per hour when SCP-074 is shielded from ultraviolet light, and approximately 29.2 times per hour when SCP-074 is exposed on filtered daylight. The globular organ at the tip of its ovipositor luminesces and emits what it was originally thought to be a form of non-ionizing radiation, but which has since been identified as coherent wave packets of the probability of one of SCP-074's self-fertilized eggs, henceforth SCP-074-1, reifying, i.e. becoming a thing, spontaneously coming into existence. Personnel who properly understand the concept of wave packets are disqualified from working with SCP-074. Instances of SCP-074-1 preferentially reify and incubate within the flesh of humans with knowledge of physics. The rudimentary knowledge of physics which even poorly educated adult citizens of a technological civilization can acquire via cultural osmosis. For example, magnets can attract or repel each other, matter is made of atoms, light has a speed, appears to be sufficient. In the absence of suitable humans to serve as hosts, the wave packets will reify within other organisms or within inanimate objects. However, rather than incubating, the eggs will wither and die, leaving perforations similar to radiation damage at a macroscopic scale. The wave packets appeared to decay over time as no wave packets or instances of wave packet related damage have been detected at distances greater than approximately 400 meters from SCP-074. The rate at which successfully incubated instances of SCP-074-1 mature appears to be dependent on the host's exposure to ultraviolet light. Within a host exposed to an average of 30 minutes of unfiltered sunlight per day for a month, an instance of SCP-074-1 was observed to grow from 2 milligrams to 8 kilograms, at which point it was surgically excised and killed. Whereas within a host totally isolated from natural light for a month, the three simultaneous instances reached sizes at excision of only 600 grams, 680 grams, and 710 grams. The complete developmental history and life cycle of SCP-074-1, including how they emerge from their host and their size at emergence, is not yet known. Lesson complete.
