Project Isorropia, negates 1861.

SCP Designation:
SCP-1861 - A meteorological phenomenon consisting of precipitation and fog composed of salt water and human fluids. A submarine (SCP-1861-A) will manifest in these events in a body of water, where then humanoid entities wearing deep sea diving gear (SCP-1861-B) will emerge from the vessel and attempt to lure anyone into SCP-1861-A. Subjects that complied with the entities claim to have been transported to a replica of earth made entirely out of water.

SCP Designation:
SCP-009 - A liquid identical to water, with the exception of a red hue and [REDACTED], that solidifies at above 0°c. Any liquid that makes contact with it will transform into SCP-009.

Containment Method:
After several D-Class personnel carrying SCP-009 filled canisters entered SCP-1861-A, no more appearances of the vessel have been made. There is currently no known way to retrieve the SCP-009 samples from the alternate reality. The SCP-1861 phenomenon itself is still active, but as it is in no way dangerous nor does it required extensive containment procedures, the anomaly has been reclassified as a Recurring Extranormal Event (REE). - Researcher Schmidt
