Item #: SCP-1255
Object Class: Safe
Special Containment Procedures: SCP-1255 is to be contained in a large concrete basin measuring 5m x 5m x 1m. Temperatures in the containment room should be kept at 10°C. Access is restricted through the use of a key card with appropriate clearance level and a 3-digit security code. The security code is to be changed once a month, or at the end of a scheduled testing period. Testing periods may last up to 1 hour and all samples must be returned once the tests are concluded. No researchers are allowed to enter SCP-1255's containment chamber, and the retrieval of any quantity of SCP-1255 will be conducted through a trained guard wearing a Class-A HAZMAT suit.
Testing of SCP-1255 must be carried out in a sterile room with vents placed only on the ceiling. The testing chamber's floor must have points of depression in a grid of 5m² to ensure that any SCP-1255 dropped will collect in easily retrievable locations. All surfaces inside the testing room must be white to ensure SCP-1255 can be located if spilled.
Vessels for the transport of SCP-1255 must be made of metals more dense than iron and are required to have air-tight seals with two additional redundancy locks to ensure nothing is spilled.
Description: SCP-1255 is a grey fluid of unknown composition and mass. When a subject touches a sample of SCP-1255, the substance solidifies and perfectly holds its shape. Solids formed out of the substance are designated as SCP-1255-1. When skin contact is broken, SCP-1255-1 loses its shape and becomes liquid again. If cooled beyond -5°C, samples of liquid SCP-1255 will freeze into a state similar in appearance to SCP-1255-1 but much less strong. If heated to temperatures in excess of 110°C, the substance evaporates into a particularly dangerous gaseous state; its anomalous properties are demonstrated in all three conventional states of matter.
Discerning the force necessary to break SCP-1255-1 has proved difficult, and seems to differ from subject to subject. Results so far have suggested that SCP-1255 is able to form a connection with the subject who touches it. If the subject is suicidal or in any way depressed, the sample will prove much more prone to cracking. If any sample of SCP-1255-1 is cleanly broken, the subject touching it will die within 3 seconds. When a subject touching SCP-1255-1 dies by any means, including but not limited to the breaking of the sample, said sample will turn into a quantity of blood in equal volume to the substance. DNA testing has shown this blood to be a perfect match to the subject in three different tests, but in all cases the blood made out of SCP-1255-1 contained no platelets. Refer to Addendum 2 for additional information.
Only one method of producing SCP-1255 has been discovered so far. The process takes approximately 1 hour and 15 minutes and requires the use of at least 1 living Class-D subject as well as several restraints. The subject must first be instructed to hold the sample. If necessary, the subject should be restrained and their hand locked in place. After approximately 30 minutes, the subject will begin to feel a deep muscular pain. After 45 minutes of exposure, personnel will lose the ability to hold SCP-1255-1, and the sample will revert to liquid form. Shortly afterwards, the affected appendage will begin to physically resemble SCP-1255-1. Gravity eventually pulls the limb off of the subject, causing it to liquidize.
The subject, following this process, will be bleeding excessively and, upon the discretion of the researcher, may either be terminated or used again to create SCP-1255. If the process takes all of the subject's limbs without killing the subject, they are to be terminated to avoid unnecessary life support costs.
Addendum 1: Testing with gaseous forms of this substance now requires authorization from personnel with Security Level 2 clearance. There are no unique properties of gaseous SCP-1255 that are beneficial. Researchers must remember that all forms of this substance are capable of producing more SCP-1255, including gasses.
Addendum 2: Recent testing has proven that a sample of SCP-1255 is capable of fracture. Tests were conducted by filling a rod-shaped mould measuring 500mL with SCP-1255. Each subject was instructed to pick up the rod, and hold it against an anvil. Then, weights were placed on the opposite end to the subject. One subject, D-12893, had a history of suicidal tendancies. His rod broke after 2 minutes and 50 kg of weight, producing 500mL of blood matching D-12893's. When the sample of SCP-1255-1 was broken, D-12893 fell to the ground and died almost immediately.
From this we can conclude the strength of SCP-1255 relates to the strength of the subject's will. If a subject is suicidal or has shown bouts of depression, an object made out of the substance will be noticeably weaker and more prone to fractures.
When the test was performed with D-24730, a mentally healthy subject, the solidified substance withstood great stress, as usual. The researchers conducting the experiment left D-24730 in the room alone with a guard, and turned off the lights. The guard was instructed not to talk to the subject, as part of the experiment. Within 5 minutes, the subject grew noticeably agitated, and a crack appeared on the rod of SCP-1255-1. 12 minutes after the researchers left the room, having been deprived of any explanation or knowledge about the test, the subject became quite still and silent. It seems that at that point, D-24730 had come to the conclusion that the test would end when the substance broke. At this point, he started trying to break his sample himself, unknowingly increasing the strength of the substance remarkably. After 5 minutes of this, the subject ceased his actions and sat on the floor, keeping his hand on the substance. It was at that moment that the subject's sample snapped completely. The subject died in an identical fashion to the first, and the sample broke into a total of 500mL of blood, identified to be the subject's.
From this, we can conclude that SCP-1255 is mildly telepathic, and reacts to the strength of will expressed by a subject. Conclusions can be drawn from the actions of D-24630 about the effects of SCP-1255. It seems that the substance projects a minor compulsion to the subject to keep its grip on the sample. This may be connected with the substance's means of "reproduction" involving consistent contact. Further testing should be done to see if there is a quantifiable amount of stress resistance that can be associated with a weaker will to live, and if the relationship is linear.
