Item #: SCP-2966
Object Class: Keter
Special Containment Procedures: SCP-2966 is to be contained at Outpost 117, and at no time shall any other SCP objects be contained with it. A liquid-fluoride thorium reactor is to be powered at all times, with the heat exchange directly in thermodynamic contact with SCP-2966's housing. Before usage of SCP-2966, monitors will ensure that there are at least 2.04×1017 joules of heat energy available to thermodynamically transfer into SCP-2966's housing. During use, this heat energy transfer will be carefully monitored to match the rate of matter removal.
A skeleton crew shall occupy Outpost 117, to minimize the risk of casualties. This crew shall consist of three persons trained in the maintenance and upkeep of a liquid-fluoride thorium reactor, four research personnel to monitor both SCP-2966's state and the state of the reactor, two four-man squads of security personnel to patrol a 25 km perimeter around Outpost 117's location and deter civilian entrance, and one D-class personnel to use SCP-2966.
A D-Class shall use SCP-2966 three times per day, at eight-hour intervals (0800, 1600, 2400), where use is defined as the removal of at least ten sheets from SCP-2966. Use is to be heavily monitored and contact shall be kept with the D-Class subject at all times during said use, in order to modulate the speed with which SCP-2966 is used. A regulator placed on the reactor shall accordingly adjust energy output to match inevitable changes in the rate at which SCP-2966 is used. A scale attached to SCP-2966's housing shall determine its mass at all times, and relay said information to monitoring staff.
Construction of an airstrip for jet aircraft is currently undergoing evaluation as a possible means of escape, should SCP-2966 reach the critical stage, as well as a means for connection to larger adjacent Foundation sites.
Description: SCP-2966 is an anomalous roll of █████ brand toilet paper. The roll currently averages a mass of around █.█ kilograms, though attempting to reduce this mass is discouraged as a result of Incident 2966-35A. Toilet paper sheets removed from SCP-2966 are, beyond being incredibly effective at removing stray fecal matter, non-anomalous and energetically stable. The roll section of SCP-2966 is housed in a steel container, attached to a wall mounting, which has no means for accessing the roll for replacement or removal. Non-invasive testing of the housing has not yielded a clear picture of what is inside the housing, and invasive testing is discouraged due to SCP-2966's volatile nature. In addition, the housing serves as the main heat-sink for thermal transfer between SCP-2966 and the reactor; damaging the thermodynamic connection may result in SCP-2966 going critical.
SCP-2966 is anomalous in that it is, effectively, an infinite roll of toilet paper. Since containment started in ██/██/████, approximately ██ km of toilet paper has been removed from SCP-2966. No means of inputting mass or more toilet paper have been observed, and [REDACTED] testing has revealed no temporal retrieval of additional paper from a different location or dimension. The mechanism by which SCP-2966 accomplishes this is entirely unknown, though its effects are well understood.
SCP-2966 obeys the laws of mass/energy conservation, and through unknown means, absorbs energy from its surroundings in order to create the matter that makes up the toilet paper. One sheet of SCP-2966 weighs approximately three grams, which means that approximately 2.04×1016 joules of energy, or roughly 65 tons of TNT, is needed for one sheet of SCP-2966 to be produced.1 It is estimated that there are ████ sheets formed within the roll of SCP-2966, or a yield of [REDACTED] megatons of TNT.
If more than ten sheets removed at one time from SCP-2966, it will absorb the energy around it at roughly the rate at which sheets are removed. The form of energy absorbed is most often heat energy, though SCP-2966 does not appear to have a preference; testing has shown that ambient sound energy has also been decreased some during use. Without an external source of energy to provide power to SCP-2966, the large amount of energy needed to form one sheet (2.04×1016 joules) is absorbed from the ambient heat of the surroundings, quickly bringing the temperature of all matter within a radius of ██ meters to near absolute zero. This has happened twice during power failures. Both times, onsite staff have sacrificed themselves to remove ten sheets, killing themselves though hypothermia instantly. While not a sustainable containment solution, such a sacrifice has prevented SCP-2966 from going critical.
If SCP-2966 is not used, it will begin to lose the matter it has gained, turned into energy once more, at a rate given as e(█.██)n joules per second, where n is the number of minutes since last use. This energy is radiated away in the form of heat, and occasionally, alpha particles. The optimum balance between usage and radiation has been determined to be slightly more than eight hours, reflected in the special containment procedures. As this rate increases exponentially, SCP-2966 will reach a critical stage approximately ██ hours after last use, in which the rate of energy radiation will rapidly approach infinity. Effectively, this results in SCP-2966 converting its remaining mass entirely to energy in an instant. This is estimated to produce roughly 1x10██ joules of energy, or an explosion with a yield of ████ megatons.2 Despite Outpost 117's remote location, a fully critical SCP-2966 situation is estimated to produce casualties in excess of what the Foundation is equipped to handle.
During usage of SCP-2966, D-Class subjects have reported an occasional decrease in room temperature. D-Class have also reported that the paper removed from SCP-2966 is exceptionally comfortable, effective, and strong. Requests for sheets removed from SCP-2966 to be re-rolled and used at Foundation facilities have been denied.
