SCP Foundation

SCP-XXXX

SCP-XXXX is a glass testing vial, estimated around 10 cm's tall. The liquidy gaseous substance in SCP-XXXX is designated as SCP-XXXX-2 and is extremely toxic, SCP-XXXX-2 is an airborne disease, traces of SCP-XXXX-2 are currently impossible and any area contaminated by SCP-XXXX-2 must be put under immediate permanent quarantined lockdown. SCP-XXXX-2's effects consist of, nausea, vomiting, black spots appearing on the subjects body and death. In case of emergency of which SCP-XXXX-2 is airborne inside the facility, the on-site nuclear warheads are to be detonated.

So… this seems to be your generic deadly magic object with disproportionate retribution emergency procedures. How is detonating a nuke supposed to do anything helpful about a deadly airborne substance? Why is the vial itself considered the primary SCP object when the gas inside it is the real anomaly?

Overall this is just another thing that kills people, and honestly, could actually exist in real-life because all it is is just a really toxic gas. Really toxic deadly gases exist in real life.

I don't think this will work as it is. Furthermore, given that this isn't your first such idea to have these conceptual problems (focuses too much on how it hurts things/its abilities rather than an interesting story to share through the medium of flash fiction), it might be better for you to take a pause on trying to force out a mainsite page. Maybe do some reading of the recently-posted successful works and get a feel for why they were well-received, rather than making wild guesses.

I can make the gas the main item, also this is why Ideas and Brainstorming is here, to build a solid foundation for something your writing.
