 Item number, SCP-292, Object Class, Euclid. Special Containment Procedures, SCP-292 is to be kept at Site 72, in a guarded room in a locked padded container set up to avoid movement of or damage to SCP-292. Access to SCP-292 is prohibited without Level 3 authorization. Incident personnel must report all incidents of deja vu or related symptoms to Site Administration. Description SCP-292 is a 60-second brass hourglass, 10 cm tall. When all its sand is at the bottom and SCP-292 is flipped over, only two outcomes have ever been observed. Either the sand runs out normally after one minute, or SCP-292 is knocked over on its side. If SCP-292 is knocked over, anomalous properties do not again manifest until all the sand in SCP-292 is in one bulb. At no time has SCP-292 ever been observed to be flipped over a second time within 60 seconds, except when knocked over as above. Any time SCP-292 is upright and all its sand is in its bottom bulb, and a subject attempts to flip SCP-292 over, with the intent to flip it again before all its sand runs out. The subject and people nearby suddenly experience deja vu. The intensity of deja vu is inversely proportional to a person's distance from SCP-292. The subject is often momentarily stunned by the experience. Persons experiencing deja vu from the same event often describe similar recalled experiences. It is believed that when SCP-292 is flipped over, a process is started in which, if SCP-292 is flipped again before its sands run out, time flows in reverse to a point a couple of seconds before SCP-292 was initially flipped. Time then flows forward again as if SCP-292 were never flipped. Deja vu would thus be a side effect of this process. Prolonged exposure to SCP-292 can cause nausea, migraines, vertigo, hallucinations, seizures, and symptoms consistent with temporal disjunction, somatic psychological, or both. Addendum 1 Experiment 292-31 Procedure Subject 0-3-1-0-1 was instructed to flip SCP-292 over, and then shoot Subject 0-3-1-0-2 to death, and flip SCP-292 back over before it runs out. Results As Subject 1 reached for SCP-292, both subjects, as well as other personnel in the area reported feeling deja vu. Subject 1 exhibited elevated levels of adrenaline, while Subject 2 exhibited pronounced apprehension in the presence of Subject 1. Addendum 2 Experiment 292-46 Procedure Subject 0-4-6-0-1 was instructed to flip SCP-292 over, wait 30 seconds, and flip SCP-292 back over. When deja vu was experienced, Subject 0-4-6-0-2 was instructed to do the same thing. When deja vu was experienced a second time, Subject 0-4-6-0-3 was instructed to do the same thing. As Subject 1 reached for SCP-292, all subjects experienced deja vu as expected. Subject 2 hesitated and was instructed to flip SCP-292. While reaching for SCP-292, Subject 2 fell to his knees, Subject 1 doubled over, and Subject 3 staggered. Subject 3 was instructed to flip SCP-292, and as he reached for SCP-292, all subjects appeared to exhibit temporal shock for 10-15 seconds before falling unconscious. Temporal symptoms subsided within 5-7 days, while visual and audio hallucinations persisted for several months more. Addendum 3, Incident 292-04 While preparing for experiment 292-75, Dr. Pratt suddenly clutched SCP-292 to his chest and reported he had just experienced deja vu. Dr. Pratt said that he felt like he was about to drop SCP-292, and if he did, something bad would happen. Dr. Pratt has hypothesized that Dr. Pratt had indeed dropped SCP-292, but instead of breaking, SCP-292 reversed the flow of time until a moment before it was dropped. If SCP-292 does in fact possess such a self-preservation system, the potential consequences, data expunged. Reclassification to Euclid approved until more information on SCP-292's properties can be gathered and analyzed. Item number SCP-276 Object Class Euclid Special Containment Procedures SCP-276 is to be indefinitely moored at Site- Docks, with access given only to personnel with level 3 clearance or higher, considering its unique qualities. No objects originating from an earlier or possibly later era that our own are to be taken onto SCP-276 due to the potential for loss of valuable materials. Regular maintenance is to be carried out after SCP-276 has been made incapable of operation due to containment issues. Description SCP-276 has a variable shape, size, and mass, but always appears to be a nautical vessel of make and model relevant to whatever era it exists in. Currently, it takes the form of a large sailing schooner, 19.93 meters or 304.9 feet in length, and weighing 1,360 metric tons. Under normal conditions, SCP-276 operates as a standard sailing vessel, capable of achieving 16.2 knots at optimal conditions, regardless of its current manifestation. On SCP-276's bridge, near the wheel of the ship, is a throttle, labeled forward, back, and back again. Usage of any of these functions will activate SCP-276's ability to travel through time, while taking anyone currently on the vessel as well. This ability is only limited by the requirement that the era in question possesses some form of boat. Attempts made to travel before the emergence of human life have failed, as well as trips made into the far future. The throttle will act in relation to the current era, with the exception of back again, which will return SCP-276 to modern time. It is unknown if operation of SCP-276 can fundamentally alter history, due to the retroactive nature of time. Any changes made would have already taken effect, and all current research into SCP-276 is related to making sure that any possible manipulation of the timeline does not occur. Of note is the anti-anachronistic nature of SCP-276. Beyond its tendency to change its form to the respective era it resides in, all non-human objects on SCP-276 will alter as well, to become time appropriate. A flashlight taken back to the early 1700s will revert to a more primitive form of illumination, such as a gas lamp. Organic life is unaffected, with the exception of creatures that either do not exist yet, or have ceased to exist. In both cases, the animal will become another species from the closest taxonomic rank it shares. Dead persons brought to modern times are similarly affected, becoming an entirely different person. Genealogical testing reveals that the subjects are data-expunged. Note, SCP-276 is not, I repeat, NOT to be used as a recreational device, especially involving exploitation of SCP-276's temporal qualities. Similarly restricting access to level 4 personnel until further notice. Dr. W. Addendum As of W. The newly formed Mobile Task Force Row 5, stitch in time, is to be assigned to, and given full security clearance involving use of, SCP-276. After taking into consideration SCP-276's ability to fix anachronisms and errors in time, all missions involving temporal tampering are to be headed by Row 5. Item Number SCP-281 Object Class Safe Special Containment Procedures SCP-281 is currently contained within Maximum Security Storage Locker 18E, on level 7 of Research Reliquary and Containment Site 76. SCP-281's lithium-ion battery pack is to remain plugged into the site's main power grid, unless used in testing. Necessary cables have been supplied and are stored with the object. Because of the nature of the object's anomalous properties, testing on SCP-281 is to be authorized by the level 4 senior member of Research staff, currently assigned to this project. Any class personnel used in testing are not to be informed on the nature of SCP-281. Description SCP-281 is a makeshift device measuring approximately 25 cm by 35 cm by 20 cm. Built into the device is a high-capacity lithium-ion laptop battery to provide power. In addition, the object incorporates a variety of components from such diverse sources as a Philips brand alarm clock, a digital kitchen timer of unknown-making model, a NEC-PC-8201A portable computer, and a USB keypad, brand unknown. Attempts to reverse engineer it have thus far not yielded any significant results. SCP-281 is currently not believed to be functioning as intended by its creator. SCP-281's effects become apparent when the following tasks are performed in the correct sequence. 1. Subject sets an alarm using the alarm clock interface. 2. Subject waits for the alarm to sound and presses the alarm clock's snooze button. The depression of the snooze button triggers the creation of a localized temporal anomaly around SCP-281. The area affected is a spherical field with an approximate radius of 6 meters, centered on SCP-281, and designated as SCP-281-1. While an item's outside this anomaly are not affected in any way, how the device creates the temporal anomaly is unknown at this time. The kitchen timer component of SCP-281 will display 9 minutes when SCP-281-1 is created and begin counting down. Setting the kitchen timer to any other amount of minutes or seconds prior to activation does not appear to have any effect on SCP-281's functioning. When SCP-281-1, time passes at a highly increased rate, with 9 minutes lapsing inside it compared to approximately 1 millisecond outside. From the perspective of those inside the temporal anomaly, time moves at a normal rate, while outside of SCP-281-1, time appears to have effectively stopped. Note, this effect is similar in nature to the Wonder Zoom feature of SCP-2445. While no link between the creation of these objects is believed to exist, examination of this documentation provides further insight into the nature of paratechnological temporal distortions. Subjects within SCP-281-1 can move around within its limits, but attempts to have subjects cross from an active instance of SCP-281-1 into an area beyond its influence, have invariably resulted in subjects undergoing massive and acute cellular disruption along the line, separating those parts inside and those outside of SCP-281-1. A similar effect has been observed on subjects and objects brought into an instance of SCP-281-1 from outside its area of effect. It has proven possible to move SCP-281-1 by transporting SCP-281 to a different location while active, but any materials, biological or otherwise, immediately suffer a massive cellular and molecular disruption as described above. The organic material present within SCP-281-1 when the device is activated is subject to normal biological processes over the period of time that lapses inside SCP-281-1. To those outside of SCP-281-1, no time appears to have passed. If subjects present in an active instance of SCP-281-1 have moved during the period of time SCP-281-1 was active, they will seem to have teleported to their new location. As the timer reaches 0 minutes and 0 seconds, the alarm sounds again and time inside and outside of the instance of SCP-281-1 are instantaneously resynchronized. Due to the abrupt nature of this event, subjects inside SCP-281-1 when the 9-minute period expires suffer effects resembling severe decompression sickness. Known treatments for that condition have been proven to be equally effective in treating SCP-281 test subjects. Addendum 281-A01 Recovery and Preliminary Containment Notes On date undisclosed, a remote monitoring station picked up encrypted transmissions emanating from a location in the mountains. After decryption, the transmissions were found to be reporting progress on a project referred to as Full Circle and SCP-281 was secured by a Foundation airborne recovery team during a raid on a fortified hiker's cabin. The device's creator, a 36-year-old African-American male identified post-mortem as Exhibited Erratic and Aggressive Behavior When Encountered. No evidence exists of an affiliation with any known GOI or other organization. Item Number SCP-224 Object Class Euclid Special Containment Procedures Item SCP-224 is to be stored in a soundproof enclosure with acoustic destructive interference nodes. Nodes must be replaced on a weekly basis by remote means due to the erratic nature of SCP-224's effect. Non-class D personnel are not to enter the enclosure. Additionally, SCP-224's enclosure must be kept free from moisture to avoid rapid oxidation. In the event that the clock begins to chime, all personnel must evacuate the area and the location should be secured following procedure ZYT-77. Description SCP-224 is a wooden grandfather clock, accented with a black lacquer and gold leaf. Markings, remotely observed, date its origin at the end of the 19th century. Though internal examination of its components has been done, the density and construction of its gears make method of function impossible to interpret. The hands of the clock do not move with any known consistency, though the tendency seems to be generally clockwise. Additionally, chimes occur at non-regular intervals, ranging from approximately one minute to several months. To further complicate matters, the numbers on the clock also have a tendency to move and shift, though they generally retain ascending order. Each chime has an anomalous acoustic signature that causes a drastic localized temporal acceleration. People and objects in range of the sound begin to age. The amount of time is not consistent with the chimes, ranging from essentially inconsequential amounts to several years, though the amount aged during any single event is consistent for all objects within the field of effect. SCP-224 was originally found in the antique shop and purchased by Mr. Wang as a gift for his wife. When brought home and wound, the anomalous properties were noticed, though not acted upon, both apparently considering the object broken. Their bodies were discovered in their collapsed house two days later, aged significantly. Foundation personnel monitoring the house took interest, and SCP-224 was subsequently recovered. Foundation agents were unfortunately lost following exposure during transportation. Any instances of SCP-224 retaining any numeric pattern for an extended period should be reported to Dr. Locke. Failure to do so will result in suspension and possible demotion. Addendum SCP-224 Catalogged Incidents Due to repeated errors on the part of the maintenance crews working on containment for SCP-224, Dr. Simmons insisted that the following report be spread among the on-site work crews to fully stress the importance of SCP-224's containment. After its circulation, it was added to the primary case file for historical purposes. Today, I had the pleasure of informing Agent Wang that he is to be given retirement pay and is free to leave active duty as of this evening. It was not initially approved by Director Wang until I explained the circumstances. Agent Wang, who is the father of Alice and husband of Mary Lee, was walking past the SCP-224 containment facility on Friday, March 17, 1981. He was reporting to his supervisor's office to deliver the final report on SCP-224, which he was instrumental in helping acquire. Since SCP-224's effect is so unpredictable, he had no way of knowing that the object had activated until the acoustic dampening equipment failed, leading to the collapse of the wall. At this time, said agent was exposed to seven iterations of SCP-224's effect. The first one saw him age into his mid-thirties. Those of you who have seen the video are aware that this wasn't a drastic change. However, by the second exposure, he was now well into his forties. There was significant graying of hair. By the third iteration, he was balding, and we estimate his age reached into the early sixties. By the fourth, his skin had noticeably wrinkled, with liver spots appearing in several places. By the sixth iteration, Agent Wang collapsed due to a broken hip, fracturing several ribs, and his left arm. It was at this time that he lost control of his bowels and bladder. When the seventh iteration ended, containment had to be manually re-established. At this time, said agent is estimated to be over a hundred years old. As a note, Agent Wang volunteered for termination and examination of SCP-224's effects, should the retirement pay he was now technically entitled to be rewarded to his family. I heartily thank Director Wang and said agent for giving us this opportunity to study SCP-224's effect. I hope you'll remember in the future that while some SCPs kill immediately, others do not. Others leave lingering effects that have ramifications for the people and the families of the people who are subjected to them. Dr. Rosmusson was down the hall from Agent Wang. He is now a 35-year-old man in an elderly body. Assistant researcher Jessup, who was pregnant when she was exposed in the same incident, died when her child was forced through her abdomen. Her son is a 40-year-old man with the mind of an infant. Dr. Quinn's undiagnosed case of bladder cancer consumed his entire abdomen in a matter of moments. Please keep these incidents in mind before failing to replace the perfectly fine acoustic nodes in the containment enclosure. Dr. Jay Simmons, Head of Containment, SCP-224, Item Number, SCP-202, Object Class, SAFE. Special Containment Procedures Research is being conducted on SCP-202 at Bioresearch Area 12. Here, researchers are actively seeking to understand and cure the condition plaguing SCP-202. He is granted full amenities of Level 0 personnel quarters when not being examined. SCP-202 is under the assumption that he is in the hospital and is not to be made aware that his doctors are in fact SCP researchers. Description SCP-202 is an Asian-British male, 41 years of age, who performs all actions in reverse. He does not appear to age in reverse, but speaks, eats, walks, and performs all other actions opposite to what is considered normal. SCP-202 speaks in reverse English with a British accent. Recording his speech and playing it backwards at one-to-one speed allows for normal communication. The subject asserts that he was a normal individual living in Stockport, England, until he woke up one morning four years ago, and found that every action he had tended to do, he did in reverse. He pledges that no matter how hard he tries, he is unable to carry out normal patterns of motion. He also claims to be unable to explain how he is able to walk backwards through crowded halls without bumping into others, or other inexplicable acts. Watching SCP-202 is particularly frustrating to Foundation biologists and physicists. Other than acting as a pump, the chambers of his heart act as vacuums, pulling his blood towards the heart in arteries, and pushing it away in veins. SCP-202 actually exhales oxygen and processes carbon dioxide. Researchers are fervently seeking answers to how his respiratory system works and if, on the molecular level, the Krebs cycle of metabolism could possibly run in reverse. His eating habits confound researchers as well, as food comes up from his stomach and out his mouth and undergoes a reverse chew. For example, when eating a sandwich, SCP-202 somehow regurgitates a bolus of food that reverse chews into a portion of sandwich. Boluses are added from SCP-202 into a complete sandwich that defies laws of both physics and biology. The resulting sandwich is completely normal and edible according to research. SCP-202 claims that he isn't aware of what he's going to eat until it starts coming. As for waste, when SCP-202 needs to data expunged, SCP-202 does not think in reverse and cannot foresee the future, as some personnel believe. He is rather good at Rubik's cubes and enjoys dismantling jigsaw puzzles. Direct order from Commander Expunged We're not having any more discussion about what happens when 202 goes to the bathroom. I think we can all paint a pretty picture of what goes on in there. The damned scientists can't explain where it comes from and neither can the plumbers, so let's just leave it at that. The poor man has enough problems. Give him the courtesy of a little privacy. Until the quacks can come up for a reason to study it, I want all data on the topic expunged.
