SCP-184 is a small metal object that makes buildings bigger on the inside. It's only about ten centimeters across, shaped like a dodecahedron with holes in its faces and little spheres at the corners. Put it inside an enclosed space and, after about an hour, the interior starts expanding while the outside stays exactly the same. At first it stretches the existing rooms. The walls move further apart without the ceilings getting higher, until the original dimensions have tripled. Then it starts adding entirely new rooms. It can even copy the things already inside, so the extra space initially looks furnished in a way that belongs with the rest of the building. That copying doesn't stay reliable. You get books made of glass, a microwave made of wood, strangely shaped rooms, and doors that open onto solid walls. Hallways become too small or turn back through long mazes. The building keeps getting bigger, but the further expansion becomes increasingly wrong. Removing SCP-184 stops more rooms from being created. It doesn't put the building back the way it was. That's a pretty important limit when the apparent attraction is extra space. Once it has changed a house, taking the little object away doesn't give anybody back their original floor plan or erase the rooms already there. It also doesn't need a house. The same effect has been observed in a cardboard box. That makes the containment rule very straightforward: don't put it inside a structure. The Foundation keeps it outdoors on a powerful electromagnet, disguised as a piece of sculpture in an area made to look like a park. The recovery story places it in Kowloon Walled City. Reports of unusual growth brought the Foundation there, and the Mole Rats eventually recovered it. Some documents suggested people had been charging fifty pounds for each half hour it spent in a home, although residents didn't confirm that arrangement. Sections of the affected city had already been destroyed, so the full consequences were never established. There's an obvious reason somebody might want what it offers. More room without needing more land sounds useful right up until the new space stops making sense. From outside, nothing has changed to warn anybody how extensive the interior has become. The Foundation's response is to keep it in the open and review affected buildings for demolition. An object small enough to pick up has made an ordinary building into somewhere that needs a rescue team before anyone investigates. https://t.co/DmoxItCPWb
