Object class: keter safe
Special containment procedures: scp-xxxx is to be contained in a 3x3x3 meter box made of layers of graphene. The room containing this box should also be lined with graphine
Description: scp-xxxx is a single atom weighing approximately 2 metric tons, scp-xxxx can move freely through air and can penetrate through almost all matter due to its weight. For unknown reasons scp-xxxx can be seen through thermal cameras. scp-xxxx seems to be attracted to living organisms and constantly moves to any organism in the area. (see addendum 2)
upon discovery scientist:████████ deemed it a keter object, fearing that its very existence would cause a black hole. After containment (see addendum 2), it was deemed safe. scp-xxxx is being contained at site-77
Addendum scp-xxxx-1
After some time of tracking scp-xxxx, scientist:████████ sent a small MTF strike force of 3 members call-sign uniform G-1 to contain scp-xxxx. [DATA EXPUNGED] members were lost. It appears that scp-xxxx can pass right through any object causing extreme damage when entering a human due to the movement of the natural flinching of the subject.
Addendum scp-xxxx-2
After examination of the footage captured during the last containment attempt scientist:████████ found that scp-xxxx is constantly moving towards living organisms. scientist:████████ sent one D-class personnel, armed with one thermal camera, to draw scp-xxxx in and contain scp-xxxx. scp-xxxx is being contained at site-77.
