The bones were splashed with molten metal.

Imagine holding a silver cup. You raise it to give a toast. All of a sudden, the wine in your cup begins to boil, your flesh turns to ash and flies away as if someone with an infinity gauntlet had willed you away, the cup melts and splatters silver over your charred bones.

The only other place where I think I was impressed by scenery of this sort was the opening to Terminator 2: Judgment Day. It seems that reality is even scarier than what our writers and cinematographers can imagine.
