Item #: SCP-789
Object Class: Safe
Special Containment Procedures: Copies of SCP-789 are to be kept rolled up and bound with two (2) extra-large rubber bands at all times, except for during experiments. No other special storage procedures are required. When not in use, they are to be kept in Dr. Heller's custody, until a suitable permanent holding place can be established.
Description: The first SCP-789 was discovered in a Bazaar in ███████ on ██-██-19██. The buyer, one [DATA EXPUNGED], accused the seller of witchcraft after 789 created a hole in his floor, and was killed in the subsequent mob frenzy. Four days later, Agent █████ arrived on-location, and discovered the rug undamaged in the ashes of a bonfire. It was retrieved, and taken to Site-██. Another 789 did not appear for ██ years, until 19██, in a rural city in Alabama, which resulted in [DATA EXPUNGED]. There are currently ██ rugs in SCP possession, with another ██ confirmed, but unretrieved.
SCP-789 appear to be circular rugs ranging from one (1) to three (3) meters in diameter, of varying designs. Chemical analysis show these rugs to unerringly be made of standard, high-quality wool, approximately 35 years old, colored with various plant-based dyes. Under most circumstances, these rugs are quite normal, excepting their remarkable resistance to damage.
When one of these rugs is spread out onto flat or uniformly-curved surface, the pattern of the rug fades from visibility, revealing beneath it a hole of the exact shape of the disappeared rug. This hole reaches to a depth identical to its diameter, or the other side of the surface it was placed upon. The inside barrier of these hole retain the chemical make-up and texture of the surface. Recent experiments have confirmed that on heterogeneous materials, such as asphalt, the rugs will "subtract" only the most common substance, and other materials will be left as-is, suspended in mid-air, unaffected by gravity, and resistant to movement in equal proportion of the strength of the subtracted material.
A hole will remain indefinitely, until willingly removed. At any time, an SCP-789 hole may be removed, and the rug retrieved, by grabbing the outer rim of the hole, and pulling away from the surface. The SCP will pull away without resistance, unless there is an object on both sides of one or both of the hole's rims, in which case, the hole will remain until the offending object is removed, at which point the rug may be taken manually.
Objects, including other copies of SCP-789, pass through the holes without incident, and under the full normal effects of the environment (winds, magnetic fields, etc.), collisions with suspended objects non-withstanding. Testing of unrolling one 789 inside of another has yet to be approved.
