Not interesting enough for an upvote.
I think this is different enough from SCP-1136 to warrant an upvote. I thought it was alright, anyhow. Besides, who says that an idea cannot be used more than once? Chances are that now and then the Foundation uncovers items that bear similarities to each other.
I thought the use of a runaway truck cover story was quite well done.
Decent idea, tone and writing need work. Not feeling charitable today.
I like it, but "the room" isn't really precise. If it's outdoor, how big is the area? if you active it outisd,e everything could just tumble around the world. Null.
I just realized, though.
The way to deactivate this (which the Foundation almost certainly won't think of, and even if they think of it, they won't do it) is to put it back on a telephone pole.
If it's on a telephone pole of the style used in █████, Oregon, the anomalous properties simply won't activate, no matter how much CO2 you pump in.
The logic of this particular SCP is actually quite simple and obvious: it's a booby-trap designed to kill anyone who steals road signs and uses them as personal wall decorations (as well as all their buddies who come over to see the new wall decorations).
If the road sign is on a telephone pole, then… well, that's where it's supposed to be.
50 cubic meters? No. There's no reason once it's in a sealed container of, say, the size of the object plus a bit for foam padding, that it wouldn't maintain an oxygen atmosphere - although I'd probably at least test it with argon or some other inert gas first. I'd also have it pointed DOWN when stored in case of breach…
Oh, and the Foundation doesn't steal, it "acquires"
I think that's an leftover from before its action depended on gases.
Has been revised due to feedback; I know certain combustible metals are kept under mineral oil, so this should be a suitable method of containment.
Oi, author, that's not gang graffiti. Those are individual tags, personal signatures of the artists responsible. Maybe say "typical of area youths" instead.
Derp. I'll go do that then. Clearly I have spent too much time on the Internet and not enough time outside in the past ten years, because I can't tell the difference.
