SCP-128: Kinetic Energy Entity

Item #: SCP-128

Object Class: Euclid

Special Containment Procedures: SCP-128 is to be held in a windowless containment chamber with blast-proof doors and walls and a ventilation system that maintains Class 100 cleanroom conditions inside. The interior of the containment chamber is to be monitored remotely by cameras welded in place with protective grating. The speakers and laser monitoring system must be similarly welded into place and protected with grating. The entry to SCP-128's containment chamber must include an antechamber with a second locked door that cannot be viewed from the chamber door.

Personnel entering the test chamber for any reason must wear ballistic armor and must not bring any loose item inside the chamber. All required equipment must be rigidly mounted to the armor. Interference with the laser monitoring system or the central wheel is forbidden unless required for maintenance.

In the center of the containment chamber, a wheel must be mounted to a concrete pedestal and allowed to spin freely. Should the wheel be measured to spin at less than 4,000 rpm at any time, all personnel are required to evacuate the containment chamber and foam nozzles will be deployed.

SCP-128 is to be kept in a chamber measuring at least 10 m x 10 m x 5 m with walls and door armored in 5 cm steel plate. All personnel who enter the containment room must wear full suits of heavy body armor, including ballistic plates. All loose objects of mass greater than 5 kg are strictly prohibited. Clothing and related items are generally considered safe, as the entity appears to be incapable of distinguishing these from their wearers. Writing utensils, loose change, and other trinkets present considerable hazards to personnel and should therefore be used sparingly never enter the containment chamber.

All items are to be cleared from room via suction before any personnel will be permitted to enter. Once personnel have exited, SCP-128 is to be given small objects, both to study its behavior and to alleviate boredom (if applicable). In the event of escape, the surrounding area will be evacuated and locked down, possibly followed by attempts to herd SCP-128 back into its enclosure. Past experience suggests that the latter is unnecessary, as the entity has shown no apparent desire to vacate the premises and will eventually return of its own accord.

Description: SCP-128 is an immaterial source of kinetic energy which can be conferred upon any nonliving solid material within line of sight of the source. The source itself is motile, with a tendency to remain along the walls or at the central wheel of the containment chamber. The line of sight is blocked by any opaque material, including lead, steel, or even single sheets of paper, but not transparent materials such as ballistic glass. Opaque radiolucent materials will contain SCP-128's range of effect, suggesting that transmission of energy occurs at visible light wavelengths, but darkness does not prevent transmission of kinetic energy.

Any loose nonliving materials within line of sight of SCP-128 are at risk of anomalous propulsion to hazardous velocities. Items under 100 g in mass have been observed to accelerate to velocities of up to 900 m/s in a period of 0.1 second, similar in force to machine gun fire. Analysis of the mass and velocity of every object undergoing acceleration indicates that the system of affected objects contains a constant linear momentum of 2,500 kg m/s, anomalously unconstrained by direction. It is therefore advisable to have many heavier items available to the object instead of fewer, lighter items.

Despite SCP-128's invisible, immaterial form, it has been determined that the entity cannot be compressed into a space under a 2 cm radius sphere. Such compression with opaque materials, however, is not advised, as dust particles within the space will be excited, generating extreme heat, potentially rupturing the compression container explosively.
