Would you like the audience to think you have a photographic memory? Would you like them to look at you in awe? Here's the technique.
Refer to an article in a magazine or passage in a book, but do it in a special way.
Pause and look up in the air as if you are thinking and picturing the publication in your mind.
Then refer to the article by page number, left or right-hand page, passage's position on the page, etc.
The audience will think you are some kind of genius.
However, we know that you are just a savvy presenter who memorized the information and delivered it with that special WOW factor.
