Unconscious seeing

This is a demonstration of a well known phenomenon, followed by a not so well known demonstration that works for some people but not all. The video shows you a sentence, then removes the sentence and asks some questions about it. 
There is a  web-site presenting the same demonstration, but not using video or speech, only text and an image. That mode of presentation is likely to be less effective, but anyone interested may wish to look at it to find some links to related material.
