Item #: SCP-2252
Laconic Containment Procedures: Because they cannot move the clothesline, the Foundation has bought the house the clothesline is next to, and built a shed around the clothesline. The shed is kept locked, and three agents live in the house to act as full-time guards.
Laconic Description: SCP-2252 is a simple anomaly with complicated effects: one end of the clothesline is anchored in normal space. The other end is anchored somewhere else. Possibly several other places. When someone grabs the clothesline, they get pulled slightly out of sync with reality, which causes them to become warped. They, meanwhile, see themselves as normal, but see everything else warped in a similar way. This is generally upsetting for everyone involved.
