Ba? Fa!
Via MadArtLab comes this amazing optical/aural illusion that you have to see and hear to believe!
Cool, isn’t it? I’ve heard (haha) of this illusion before — it’s called the McGurk effect — but it’s still fun to see it done this way. When the man is shown side-by-side saying it, switch your attention back and forth between them with each syllable. Even knowing it’s an illusion, it’s still overwhelming. I can’t not hear it.
Must admit, Bad Astronomy is a seriously fantastic blog...
