SCP-251
SCP-251 is a little snow globe that the Foundation keeps under armed guard. Nobody is allowed to be alone with it, regardless of clearance. The file is short, but the difference between the size of the object and the severity of the rules gets your attention pretty quickly.
The snow never stops falling. It hasn't been moved since arriving at Site-19, so this isn't somebody periodically shaking it. There is a continuous little blizzard inside, surrounding scenes of violence and death. Some of those scenes involve fantastical things, but most depict more recognizable forms of brutality.
Photographs taken over time show that the contents change. When several people look at it directly, though, the scene appears motionless apart from the falling snow. The file doesn't explain exactly what changes when someone is alone with it. What it does say is that everyone who has been alone with the globe subsequently displayed extreme violence, xenophobia, and emotional distress.
That combination is pretty ugly. There is a clear change in how these people behave toward others, along with distress of their own. The article doesn't tell us that they join one specific ideology or receive some detailed message. It gives the observed effects and leaves the mechanism unknown.
The containment response is severe enough that anyone discovered to have been alone with it is treated as violently hostile and killed. There isn't an observation period described in the procedure, or an attempt to determine whether this particular person has started showing symptoms. Exposure itself is enough for the order.
Meanwhile, screaming, gunfire, and the sound of fires come from inside the container. The staff are told those sounds are normal. So the object is locked away, nobody is supposed to be near it alone, and whatever is happening inside can still be heard outside.
This is one of those early SCP entries that leaves almost everything beyond the immediate danger unexplained. We don't know who made it, where the scenes come from, or whether anything inside is experiencing them. The little decorative object remains on the shelf with the snow falling, while the people guarding it are expected to ignore the sounds.
