Video summary

SCP-903 is an incomplete utility tunnel connecting the containment wing to the Lambda Laboratory Wing, originally designed as a secure transport route before an incident caused it to gain anomalous properties. The tunnel features a monorail system and emits its own light from a spiral painted on the walls, though this illumination vanishes when an object or organism is placed inside the cart for transit. After approximately fifteen seconds of darkness, the cart resumes its journey, but the item transported through it has vanished without a trace, leaving behind a new anomalous object designated as SCP-903X along with a handwritten note. These generated instances possess unique and varied anomalous abilities that seem to correspond to specific SCPs that were previously moved through the tunnel before the original incident occurred. The nature of the objects produced by SCP-903 ranges from a pineapple that autonomously attacks people who tell bad jokes to a shard of obsidian that morphs into a perfect image of anyone who cuts themselves on its edge. Other notable instances include a ninety-ton bronze key that allows any door to be opened if one has the strength to lift it, and a pack of cigarettes that induces a hallucination where the smoker feels constantly watched by a one-eyed woman. Despite their bizarre capabilities, all SCP-903X instances deteriorate and lose their anomalous properties within two hours of being removed from the tunnel unless they are destroyed beforehand, while the accompanying handwritten notes remain stable and non-anomalous. Analysis of the ink, paper, and handwriting used in the notes has failed to identify a source, yet the text strongly suggests that SCP-903 is connected to a sapient entity capable of creating these unique items. This mysterious intelligence appears to be an artist or creator who occasionally runs out of inspiration, as evidenced by the final addendum where the tunnel produces only a single note pleading for help after four years of operation. The transcript concludes by inviting viewers to explore related content, specifically SCP-902, which is presented as the next step in this educational series about containment procedures and anomalous phenomena.

[music] Item number SCP 903. Object class: Uklid. Special containment procedures. Access to either side of SCP 903 is to be restricted to authorized research personnel only. The entrances must be sealed and kept under surveillance at all times. During testing, under no circumstances are personnel to enter SCP 903 or attempt to cross it. Any persons attempting unauthorized entry will be subject to lethal force. Any test subject or item that is passed through or emerges from SCP 903 must be immediately destroyed once testing is concluded. Description: SCP 903 is an incomplete site 19 utility tunnel that connects the SCP containment wing with the Lambda Laboratory Wing. The tunnel is 3 m in diameter, 50 m long, and buried approximately 5 m underground. Because of its incomplete nature, SCP 903 is an empty concrete tunnel that contains no piping, wiring, or other utility equipment. SCP 903 also contains an old rail system that consists of a single monorail that spans the entire length of SCP 903. SCP 903 was originally used as a discrete and secure method of transporting SCPs from the containment wing directly to the Lambda Laboratory Wing. However, this practice was discontinued shortly after incident 9031, where the presiding personnel violated standard operating procedure and transported several SCPs at once rather than one at a time. The resulting incident is most likely what caused SCP 903 to obtain its current anomalous properties. At first glance, SCP 903's most obvious feature is the fact that the entire tunnel is completely visible despite the lack of any internal lighting. The lighting appears to be emanating from the white line of paint spiraling around the tunnel walls. It is unclear how this phenomenon works. The Montorail system still functions as normal. However, if an item or organism is placed inside the Montreal car and sent through SCP 903, the Montreal will suddenly and inexplicably stop in the middle of the tunnel. The anomalous illumination will then deactivate, reducing visibility inside SCP 903 to zero. Attempts to use external lighting or image enhancement technology such as infrared or night vision equipment have proven ineffective in observing SCP 903 during this state. After approximately 15 seconds, the anomalous illumination in the Montreal cart will reactivate and the cart will continue on its path like normal. However, the item or organism that was previously placed inside the cart will be missing with no trace. After an indeterminate amount of time, SCP 903 will activate the Montreal cart on its own. Once the cart reaches the center of SCP 903, the illumination will shut down for 15 seconds, similar to a deliberate activation. [clears throat] When SCP 903 reactivates, the monorail card will contain a new item designated SCP 903X and in most cases, an elaborately handwritten note. The instances of SCP 903X that SCP 903 itself generates are all universally anomalous in nature, and each instance possesses different anomalous properties. However, each instance's properties seem to consistently match properties of SCPs that had previously been transported through SCP 903 prior to incident 9031. Once the instances of SCP 903X are removed from SCP 903, they will deteriorate and lose their anomalous properties after approximately 2 hours, assuming they weren't already destroyed beforehand. The handwritten notes included with the instances of SCP 903X suggest that SCP 903 is somehow connected with a sapient entity capable of manufacturing instances of SCP 903X. Attempts to trace the source of the notes based on composition of the ink and paper as well as handwriting analysis have so far failed to produce any results. However, the handwritten notes are not anomalous and do not deteriorate like instances of SCP 903X. List of notable SCP 903X instances and notes. SCP 9031, a pineapple that autonomously launches itself at any individual that makes a subjectively bad joke. Accompanying note. I thought the tomatoes were such a hoot, so I thought I'd give it a try with a different fruit. SCP 9035. A shard of obsidian carved into a humanoid shape. Whenever an individual cuts themselves on its edge, SCP 9035 morphs into a perfect image of that individual. Accompanying note: For the price of a little pain, you'll have a little buddy to keep you sane. SCP 90312. A bronze key that weighs 90 tons. Accompanying note. With this, you can open any door if you have the strength to get it off the floor. SCP 90320. A pack of Blue Lady brand cigarettes with a picture of a blue-haired female with one eye. Anybody who smokes one of these cigarettes is temporarily afflicted with a condition where they are convinced a oneeyed woman is staring at them. Accompanying note: Take a puff if you dare. If you can withstand her unbreakable stare. All other instances of SCP 903X omitted. For a full list, please file a request to Dr. Ryan. Addendum. After 4 years of containment [music] and testing, as well as cataloging all instances of SCP 903X produced, SCP 903 reactivates and produces only a single handwritten note. Even the greatest minds can lose their inspiration. Can you please help an artist in desperation? Lesson complete.
