There was a huge explosion yesterday in Tennessee at plant that made explosive material for the military and industrial projects. https://www.newsweek.com/tennessee-explosion-update-no-survivors-found-at-volatile-scene-10865405
Video from a news chopper on the scene right after the explosion shows what looks like green almost glowing debris on the ground https://www.instagram.com/reel/DPooHZbDiee/
Any idea what it is?
As far as I know it's common pratice to include chemical markers in explosives unique to the factory, so if the explosive get stolen/used in an unauthorized manner the investigators can trace back were they were trafugated.
Maybe they also include high visibility pieces of plastic as a visual markers. If so on them there would be printed some identifying information like lot number, manufacturing date and factory address.
