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?
