SCP-XXXX: Salt Cube
rating: 0+x


Item #: SCP-XXXX

Object Class: Safe

Special Containment Procedures: Revised as of Incident XXXX. SCP-XXXX is to be contained in a locked, hermetically-sealed storage container, constructed of titanium no less than 1 foot thick. The container must be able to withstand, without damage, up to 16,000 psi worth of external pressure, and be completely watertight under all circumstances. SCP-XXXX's storage container must have three locks: one retinal scanner tuned to at least one member of O5 Command, one electronic keycard lock requiring at least Site Director approval, and one physical lock with no key. If the container must be opened for any reason, a key must be created for the lock; afterwards, the lock must be replaced and the key for the old lock melted down completely.

No water may be handled within 20 feet of SCP-XXXX at any time except during testing. Testing of SCP-XXXX is forbidden without unanimous approval from O5 Command as of Incident XXXX.

Description: SCP-XXXX is a collection of cubes, combined length one inch, resembling eight pieces of fused sodium chloride. The object has no scent or taste; visual inspection reveals no discrepancy between it and non-anomalous salt cubes and its texture does not differ from them. SCP-XXXX weighs exactly three ounces. Despite this, SCP-XXXX has been shown to rapidly sink in any volume of water, descending at a rate of one foot per second in the water until it reaches a solid surface.

Chemical analysis of SCP-XXXX has revealed that the cube has anomalously high physical properties. The density of SCP-XXXX is comparable to a singularity, and is measurable at a functionally infinite density of salt. How this density is maintainable at its current level without the formation of a black hole is uncertain, as is how the object's other physical properties such as weight maintain their present values in spite of its density.

SCP-XXXX appears to be immune to damage through conventional sources, including ballistics, incendiaries, and explosives. Testing has also shown that individual cubes cannot be detached through any currently-known means.

SCP-XXXX's primary anomalous property manifests when it enters any volume of fresh water. While partially submerged, SCP-XXXX behaves as a normal salt cube, salinating the water as could be reasonably expected from a cube of its size, albeit without losing any mass or surface area. However, when the object is completely submerged, the entire body of fresh water, regardless of size, becomes instantly salinated to a concentration of roughly 35 g/kg. Extensive testing has revealed no upper bound on the amount of water SCP-XXXX may salinate at once.
