"Dr. Wondertainment's Jumbo Frisbee-rang"
Item #: SCP-5141
Object Class: Safe
Special Containment Procedures: Testing or handling of SCP-5141 is only to be authorized by level 3 staff or higher, with a written documentation of planned usage provided. Testing may only be permitted within a secure testing chamber with the following measurements to avoid incident; chamber must be 10 x 10m or larger, walls must be 17.78cm thick or thicker, ceiling must be 9.144m tall or higher.
SCP-5141 is to be kept in a secure storage locker under patrol surveillance at all times. Unauthorized access to SCP-5141 will be met with punishment up to, and including, termination considering the object's weaponizing capabilities.
Addendum: All D-Class testing with SCP-5141 has been suspended following incident 5141-a. Twenty-four hour, video surveillance of storage locker 5141 has been put into effect. Despite having the "Dr. Wondertainment" name affiliated with it, this object is not a toy and should be handled with extreme caution. - Dr. T
Description: SCP-5141 is a large, silver, plastic disk measuring 79cm in diameter. The title "Dr. Wondertainment's Jumbo Frisbee-rang" is faded on the convex side of the object. The plastic portion of the object is nearly indestructible and can withstand high amounts of damage, see testing logs for details. Testing has revealed trace amounts of [REDACTED] fused to the fibers of the nylon plastic, giving it it's near invulnerable capabilities. An outer ring, consisting of titanium alloy, [REDACTED], and gold alloy, is fused to the object, seemingly welded by anomalous means. This metallic ring is filed down to create a bladed edge surrounding the plastic disk.
When SCP-5141 is thrown by a human subject, it maintains a steady forward motion and speed until it reaches approximately 37m from the thrower. The object will then slowly come to a stop mid-air and return back to the subject. Interestingly, the bladed ring will not cause any physical harm upon being caught by or impacting the subject. When SCP-5141 is thrown at a wall, the object will repel directly back to the thrower. If the subject has an intended target, SCP-5141 will direct itself at the target when thrown then return to the subject.
SCP-5141 was acquired during a raid on a warehouse where a black market auction, hosted by Marshall, Carter, and Dark ltd., was being held. Several high volume POIs were apprehended from this event. Many had great interest in SCP-5141, as it was the flagship object for the event.
Addendum:
Test Log 5141-01
Location: an outdoor firing range to test SCP-5141's durability.
Testing Conditions: Several 45mm rounds were discharged using an M4 Carbine from a distance of 200yds.
Result: Little to no damage was visible on SCP-5141's surface.
Testing Conditions: A single 51mm round was discharged from a Mk14 EBR with an extended barrel attachment for increased round velocity at a distance of 400yds.
Result: A noticeable scorch mark was left on SCP-5141's surface, but surface was not penetrated.
Testing Conditions: A single .50 Caliber round was discharged from a standard M82 sniper rifle at a distance of 1200yds.
Result: The round successfully penetrated SCP-5141 by only 3.048mm.
Testing Conditions: A single rocket was discharged from an RPG at a distance of 700yds.
Result: Force of the explosion knocked SCP-5141 from its secured location, but no damage was done, aside from several scorch marks.
Test Log 5141-02
Location: A secured testing chamber measuring 6m x 6m with a 3m ceiling.
Testing conditions: D-9807B was given SCP-5141 and told to throw the object forward once all personnel had exited the test chamber.
Result: D-9807B threw SCP-5141 at the north wall with significant force. The object bounced off the wall and flew back towards D-9807B. D-9807B ducked to avoid the incoming object. SCP-5141 proceeded to ricochet off the walls of the testing chamber, gaining speed with each bounce. The object eventually, after reaching speeds of 194kph, embedded itself in the west wall of the chamber.
Notes: In order to proceed with testing of SCP-5141, thicker testing chamber walls must be brought into consideration. - Dr. T
Test Log 5141-03
Location: A secured testing chamber measuring 10m x 10m with a 9.144m tall ceiling, and 17.78cm thick walls.
Testing Conditions: D-9807B was given SCP-5141 and told to throw the object vertically against the floor once all personnel had exited the test chamber.
Result: SCP-5141 ricocheted off the floor, against the east wall, off the ceiling and back into D-9807B's hand. D-9807B expressed great amusement with this and continued to preform the same testing action until told to end the session.
Test Log 5141-04
Location: An outdoor firing range.
Testing Conditions: D-9807B was told to throw SCP-5141 at a cinder-block situated 400yds away.
Result: SCP-5141 maintained a steady course towards the target until it reached 35yds at which point it slowed and returned to D-9807B.
Notes: It appears that SCP-5141 cannot exceed a 30-40yd radius from its thrower before it loses momentum and returns to the thrower. Firing range tests have ceased. Returning to indoor testing chamber. - Dr. T
Incident Report 5141-a 04/15/[REDACTED]
During an attempted test, D-9807B broke protocol by throwing SCP-5141 out of the test chamber doors before all personnel exited the chamber. Two junior researchers were severely injured by the object and a patrol guard was decapitated. D-9807B was immediately terminated by guards. SCP-5141 continued to ricochet through the facility halls, gaining top speeds of 483kph. The object eventually broke into the D-Class holding wing, killing 17 D-Class and an officer. All attempts to quarantine SCP-5141 were met with failure until the object became embedded in SCP-[REDACTED] containment cell door.
Additional notes: It would appear that the 17 D-Class killed in the incident were documented to have physically assaulted D-9807B several days prior. The officer that was killed apparently assaulted D-9807B for suspected contraband possession, despite D-9807B having a clean record for the majority of their sentence. The incident has also brought another interesting revelation to light; SCP-5141 traveled a total of 460yds to dispatch the desired targets. It would appear that SCP-5141 has no limit to travel distance when bouncing off surfaces, as opposed to a straight line. Further test will have to be conducted to determine this. Also, testing with D-Class has been terminated. Only authorized, level 3 personnel may preform testing. Low level researchers need approval from myself, or a level 3 personnel. - Dr. T, SCP-5141 Head Researcher
