Salvaging of submission for Experiment Log T-98816-OC108/682

I had written up a test to kill/contain 682, but I haven't actually joined yet and therefore let the idea sit because I was busy. In the meanwhile, a similar (and admittedly more efficient) test involving part of my method was submitted, and I'm wondering what (if anything) is salvageable from my initial concept.

~Here's the existing test:

Item: SCP-272

Tissue Test Record:

Termination Test Record:

SCP-682 is released into enclosure amidst a circular array of thirty (30) two-thousand-watt (2,000W) stadium lights, of which only one (1) is switched on. SCP-272 is dropped onto SCP-682's shadow, and embeds itself in the reinforced concrete as expected. SCP-682 quickly discovers that it is trapped by SCP-272's presence in its shadow, and starts to attack SCP-272. SCP-682 then stops midway through its attack, examines 272 closely, bellows "[DATA EXPUNGED]", and slowly backs away from 272.

All thirty stadium lights are then switched on and off in random stroboscopic "disco" pattern, at 4 Hz. SCP-682 is forcibly hurled around the enclosure in random directions, in accordance with the stroboscopic pattern, and sustains heavy damage.

After fifty-five (55) minutes of this process, >95% of SCP-682's epidermis has been abraded away, its anterior left limb has been severed, sixty-three (63) of its teeth have been broken out of its jaw, and its skull has been fractured to the point that both its eyeballs have been dislodged from their sockets. At this point, SCP-682's exposed sub-dermal tissue begins to luminesce. The luminescence rapidly increases until it is brighter than the stadium lights, which eliminates SCP-682's shadow entirely. SCP-682 then collapses, and is no longer affected by the stroboscopic pattern.

SCP-682 continues luminescing for forty-eight (48) hours, remaining immobile for the duration; D-class personnel who recovered SCP-272 from the enclosure were not attacked, but sustained permanent retinal damage from SCP-682's luminescence despite wearing eye shields. After 48 hours, SCP-682 resumes normal activity.

Note: How did 682 know not to attack 272? Did it recognize the artifact? Was it able to read the glyphs carved into 272's surface? If 682 is literate, is it vulnerable to textual memetic-kill agents? Suggested methods for a viability study are welcome.

~And here's my rough submission:


Tissue Test Record:N/A

Purpose of Test:
To determine if SCP-272 is a viable method to facilitate re-containment in the event of a containment breach of SCP-682. It is believed that this will serve as a stronger restraint than most other means, given the reaction SCP-272 causes when damage is inflicted upon it.

Termination Test Record:Eight (8) stadium lights, positioned on a computer-controlled track, mounted around circumference of SCP-682's containment unit. A robotic arm is set on a mechanical track built into the walls of the containment unit, with small access points to the containment unit at various points along the track. One light is activated, pointed at SCP-682 at a low angle so as to create a long shadow across the ground, terminating at the edge of the far wall. A robotic arm applies SCP-272 to the shadow. SCP-682 shudders slightly at this point, possibly sensing the effects of SCP-272. The stadium light is then raised very rapidly, dragging SCP-682 across the ground. As SCP-682 nears SCP-272, the robotic arm retrieves SCP-272 and retracts it into the wall. SCP-682 regains its footing, and the robotic arm repositions on the other side of the containment unit. A second light is activated to cast SCP-682's shadow and the process is repeated, dragging SCP-682. As the third light turns on to repeat the process again, a lump is noted growing out of the end of SCP-682's tail. As the light begins to move down the track, the lump on SCP-682's tail bursts to reveal a blindingly bright ball of light. SCP-682 positions its tail so that its shadow continues to be cast across the room on SCP-272, and subsequent applications of lights are unable to move SCP-682.

Notes: Not as good as I'd hoped for, but at least we can contain 682's movement on one axis. That's a start, right?

Items: SCP-283, SCP-272

Tissue Test Record:N/A

Purpose of Test:
Given the results of the last test, we will attempt to circumvent SCP-682's aim by giving it a smaller moving target, the desired goal being a technique to recapture SCP-682 on escape by pulling it into containment.

Termination Test Record:After revisions to initial procedure, robotic arm is modified to also hold SCP-283. The eastern wall of the containment unit is replaced with 15 layers of thick, loose weave titanium mesh, and a long "runway" containment hall behind it. Light is activated to cast SCP-682's shadow on SCP-283 and SCP-272, both are released by the robotic arm to fall eastward through the titanium mesh. SCP-682's tail bulb activates, casting a shadow on the rock. SCP-682 is jostled as the rock clatters through the various layers of the mesh. Exiting the mesh, the rock quickly gains speed and falls across the plains outside. Just as rapidly, SCP-682's tail glows brighter to continue casting a shadow from such a distance. As the rock approaches terminal velocity, SCP-682's tail begins to emit several types of radiation outside of the visible spectrum, including two not supported by the current quantum theory of light. Bracing itself, SCP-682 lunges its tail over its back, causing the shadow to be cast directly under itself, and causing both 2CP-283 and SCP-272 to emit a sonic boom as they are pulled back by SCP-682's shadow, ripping a clean hole through the titanium mesh weave and leaving a small crater at SCP-682's feet. Turning to the wall between SCP-682 and the control room, SCP-682 jumps and rapidly moves it's tail under itself, resulting in the loss of a contact shadow at its feet and sending the rock flying through the air with another sonic boom, punching a clean hole through the wall and any equipment and personnel it made contact with. Returning it's tail to an upright position, SCP-682 causes the rock to return to its feet, blowing another clean hole through anything that was now in the way of the first hole. SCP-682 continued to volley sonic rock attacks at the control room for nearly a minute, at which point it began shooting out the remaining inactive lights. Seeing its intent, a surviving technician in the control room activated the remaining lights, and the two functioning spotlights successfully cast a shadow at SCP-682's feet, causing the projectile to fall to the eastern side of SCP-682's shadow on its next return.

SCP-682's tail bulb persisted for three days, bombarding its containment unit with numerous types of radiation, after which it was absorbed by the tail, and immediately expelled through SCP-682's mouth in the form of a short-range laser blast, breaching containment. For the following 5 days, materials caught within the blast that weren't outright destroyed interacted strangely with light, casting a faintly glowing shadow that emitted light in the violet and ultraviolet wavelengths. Partially affected materials such as damaged walls displayed this property as a gradient, with the modified shadow only appearing in parts of the shadow cast by the damaged portion of the material. When tested on SCP-272, the shadows of individuals injured by the blast seemed to tug slightly on 272's anchoring, but otherwise behaved according to 272's normal effects.

Notes: This is the first instance of a shadow being able to pull SCP-272, rather than vice versa. Needless to say I am very interested in the properties of the light that 682 managed to emit. Also needless to say, we should think long and hard before introducing any more effects to 682 to that bypass the normal rules for things like velocity.
