Instead of air, I suggest Christmas present wrapping paper. Just for spite.
That would result in a twist ending. An act of such sheer pure evil would instantly catalyse his Tom Riddleness and transform him into Voldemort v2, complete with snake face and glowing red eyes.
But the reason I suggest air is that once it disperses it cannot be Finite Incantatemed or Reparoed or targeted by any magical effect we know of. We don't know if Philosopher's Stone transfigurations are permanent in every sense or just in the duration sense, and you do not want any possibility of someone bringing Voldemort back with a first-year spell like Finite Incantatem.
Two new short chapters! Since the next one is coming tomorrow and we know it'll be short, let's use one thread for both.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 105 (and chapter 106, once it comes out tomorrow). EDIT: based on Alsadius' comment about thread creation for MOR chapters, let's also use this thread for chapter 107 (and future chapters until this nears 500 comments) unless someone objects to doing so. Given that this is the final arc we're talking about, thread titles should be updated to indicate chapters covered.
There is a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:
