Item #: SCP-4717

Object Class: Euclid

Special Containment Procedures: SCP-4717 is contained in a 500x500x500 meter containment cell with a 400 meter looped track. The walls of the containment cell are coated in MLV rubber, to block the sound from reaching water. No water or anything containing water is to be within a 550 meter range of SCP-4717. The walls are coated in bleach to eliminate any microorganisms. Dehumidifiers are placed throughout the containment cell, eliminating any humidity. No personnel are to enter the room containing SCP-4717 without a member of the O5 council’s approval. With O5 approval, a D-class personnel will be sent in to carry out whatever task is required.

Description: SCP-4717 is a marching band consisting of 250 musicians [called SCP-4717-1], and 240 instruments [called SCP-4717-2], moving at 5 kilometers an hour. Water exposed to the sound are vibrated in such a way that it splits into hydrogen and oxygen, causing the hydrogen to detonate. This includes water that makes up an organism. Whoever water based fluids are not affected by the sound. SCP-4714 will not perform unless a conspicuous water source is nearby. This includes bodies of water, and the water in a multicellular organism. If no conspicuous water source is nearby, then SCP-4717 will not perform, and continue to move aimlessly, unless certain circumstances are met.

SCP-4717, if on a looped track will continue to loop on the track indefinitely. If obstructed while there is an absence of a conspicuous water source, SCP-4717, will begin to play, causing microorganisms and humidity in the air to explode, eliminating the obstruction.

Individual Instances of SCP-4717-1 appear to be faceless humanoids. DNA from instances of SCP-4717-1 is identical to other instances of SCP-4717-1.

***Addendum-4717-01: SCP-4717 was originally discovered in the California wilderness on
3 / 14 / 25 via airborne drones. The presence of SCP-4717 caused various wildfires in the California wilderness.

Addendum-4717-02: MTF-Nu-16 is deployed to detain SCP-4717 on 3/16/25, equipped with full body MLV rubber body suits, MTF Fusion Rifles and Pistols, and Tilda/Cimmerian Reality Vacuum Attachments.

Addendum-4717-03: SCP-4717 is subdued and captured by MTF-Nu-16 on 3 /16/25. Due to the nature of SCP-4717, Site 49 is built around SCP-4717.

Addendum-4717-04: Testing is done on SCP-4717-1. SCP-4717-1 and SCP-4717-2 where seperated and placed into separate containment cells on 2/8/26. SCP-4717-1 was placed into a containment cell with a puddle of water. After 30 minutes of exposure, SCP-4717-1 was unable to separate the water molecules.

Addendum-4717-05: Testing is done on SCP-4717-2 on 2/20/26. D-10682 was ordered to play SCP-4717-2 in front of a puddle of water. The water molecules split, resulting in the loss of D-10682. It was concluded by researchers that SCP-4717-1 cannot split water molecules without SCP-4717-2. Unanimous decision was made by the research staff to place SCP-4717-2 in a separate containment cell.


Item #: SCP-4738

Object Class: Euclid

Special Containment Procedures:

Description: SCP-4738 is an unbranded 1 liter thermos mug with a what appears to be a pocket dimension. The mug contains objects within a 3 dekameter radius of the thermos. Objects within the radius dematerialize into the pocket dimension of SCP-4738 after a period of 8-9 hours. The floor, walls, ceiling, and gasses are unaffected .

If an Object in the radius of SCP-4738 cannot fit within the thermos, are broken down into smaller parts as it dematerializes into the pocket dimension. These smaller objects are capable of fitting into the thermos. For Example, if a glass vase is within the radius, it would break into glass shards as it enters the pocket dimension.
