I was thinking about Kitt Pride, XMen, and her super power to phase through solid objects, yet not sink through the floor or lose her clothes, but just wondering if she was kind of outside of our reality and not actually interacting with the molecules. Which made me wonder, if you weren't interacting with the air molecules, would you make any noise? Whether attempting to talk or what not.

I'm guessing the answer is no, but just curious what others thought.
