Posting this from home. Turns out it was a real fire, albiet a really weird one. It wasn't even reacting to the water the firefighters used, just evaporating it before it got near. I'm not an expert on fire but I've never heard of that happening before. It didn't seem to be spreading much at least, so the school might not burn down.
I saw a woman in the fire, guessing she was a teacher. It was pretty disturbing, seeing someone burn like that. I'm gonna see if I can find out who she was.
