A photo of [undecided] during recovery
Item #: [undecided]
Object Class: Euclid
Special Containment Procedure: [undecided] is to be contained in a 70m x 70m chamber; the chamber is entirely made out of AISI 6150H alloy steel; the walls, ceiling, floor and entrance are to have tubes of Glass-Clad Polycarbonate (radius = 5cm.) inserted into them at rate of
200 tubes/m; the tubes are to have saline water from the north sea located at the coast of Bremen, Germany, constantly running through it and to be renewed periodically by a specialized saline water replacement machine, as to ensure that water is constantly running through the chamber. The chamber is to have mass loaded vinyl panels placed all over its interior.
A hallway which leads directly into the chamber is to be guarded by four foundation personnel at all times (two in front of the entrance to the hallway and two in front of the entrance to the chamber). The hallway is to be made out of AISI 6150H alloy steel and is to have the same tubing mechanism and water as the chamber with a separate saline water replacement machine from the chamber's; the hallway and, by extension, the chamber require level 3 security clearance to be accessed by foundation personnel.
If the entrance to the chamber is requested, then the entrance to the hallway has to be sealed and UNDER NO CIRCUMSTANCE be opened until the entrance to the chamber is sealed again, failure to comply will result in immediate termination.
Personnel who guard and enter the chamber are to be provided with noise-cancelling headphones which have saline water running through them and are instructed to keep them on at all times, removal of the headphones will result in immediate termination, personnel entering the chamber are permitted no longer than 90 minutes inside the chamber before being asked to exit, failure to comply will result in immediate termination, personnel who exit the chamber are to be subjected to immediate physical examination. personnel guarding the chamber are to be replaced periodically every 120 minutes and are to be subjected to physical examination.
Description: [undecided] is thought to be a type VII German submarine and will henceforth be referred to as the submarine. Due to the nature of the submarine, it is difficult to ascertain the exact type the submarine is (see addendum 3 for more information). The submarine is encased in a shell of high-density polyethylene whose shape and colouration resemble that of the depiction of the "yellow submarine" from the popular English rock band The Beatles. The date 27/1/1945 is engraved on the left side of its bow alongside other engravings, all attempts to restore the remaining engravings have failed.
The song "yellow submarine" is heard playing from inside submarine, its exact source is still unknown, the song loops seamlessly without a clear indication of the beginning of each new loop at an intensity of 127 dB; the song has an anomalous and severely cognitohazardous effects, which vary in severity depending on the duration of exposure to it, detailed here:
- Phase 1 (45-60 seconds):
-Acute cephalgia or migraines.
-Nausea.
-Severe fatigue.
-emesis or vomiting.
- Phase 2 (60-95 seconds):
-Amaurosis fugax or temporal blindness.
-petit mal seizure.
-temporary paralysis
- Phase 3 (95-180 seconds):
-grand mal seizure
-hematemesis
-hemorrhagic stroke
-Thoracic aortic aneurysm.
- Phase 4 (180-240 seconds):
-severe and rapid neurogenesis, a continuous multiplication in nerve cells production causing severe swelling of the brain and causing the skull to █████████ and the eyeballs to ████████████████, death usually follows(see addendum 2 for more information).
Through multiple tests, it has been proven that the cognitohazardous effects manifest through exposure to the soundwaves produced by the music and not the music itself, yet it is most severe when exposed to the ear canal; examination of the soundwaves has shown that it is completely identical to the version that is currently accessible to the public.
When the sound waves are passed through saline water its cognitohazardous effects become weakened, as in that the "phase 1" symptoms start appearing in 2 hours instead of a few minutes and is most effective when water from the north sea coast of Bremen, Germany, the place where the submarine was recovered(see addendum 1 for more details about the recovery)
