Dust

From the New Yorker review of War of the Worlds:

"Tom Cruise, as Ray, a Jersey dockworker and lousy father, will either succeed in protecting his two kids as they all scurry across the countryside or get pulverized into white powder along with everyone else."

David Denby is a very good movie writer, and I do wish he hadn't written that. "Pulverized into powder" is exactly akin to saying "liquefied into liquid". "Powder" and "pulverize" come from the same Latin root: in fact, "Pulver" is the German word for "powder". You can't pulverize something into anything except powder, and adding the adjective "white" doesn't take the taint off a redundant construction.
