I've got a pyromaniac who's set many fires before and knows what he's doing. What he doesn't know is that the warehouse he's burning down has a large supply of fourth-of-July firecrackers--the type that are sold to the general public.
So. What exactly will happen when the fire reaches these explosives? Will they actually go off in a pyrotechnic display? Will they turn the city block into a smoking crater?
As always, I appreciate the help!
