Item #: SCP-3902
Object class: Keter

This unusual substance seems to be excreted by SCP-173, and was initially reported to be a mix of feces and blood with no anomalous properties.

This timeline is to be referred to whenever tests are being performed on any instance of SCP-3902

SCP-3902-A, The sample is younger than two weeks. Brown in color and has water-like viscosity. Contains blood of unknown origin, and feces. Completely benign
SCP-3902-B, The sample is older than two weeks and approx. 36 hours. Dark beige color and non newtonian in consistency Contains blood of unknown origin, feces, and microscopic "strings" of steel.
SCP-3902-C, The sample is now mobile to a degree.

The anomalous properties were first found when a routine cleaning was missed due to [DATA EXPUNGED]. A thicker layer of the substance had seemingly replicated itself during the short additional time it took to take care of [DATA EXPUNGED], and had become more viscous, and taken on non-newtonian properties. A sample was collected to be studied, and the rest cleaned up and neutralised in the incinerator; as per cleaning customs with SCP-173. The sample contained: feces, Blood of unknown origin, and microscopic strands of steel . After the scientist tasked with researching the substance took her scheduled twenty minute lunch break, the sample had grown to double its initial size. It had also moved a few centimetres from the microscope it was placed under. Dissimilar to SCP-173 the specimen can move when it’s in sight. When this sample was analyzed it contained
