Quirk of Nature

Richard Wiseman posts a variety of videos under the Quirkology brand.  Though ostensibly they're magic tricks, often they're more appropriately optical illusions.  As such, he generally shows how they're done.  And he does all this in a charming, whimsical way making his little excursions treats.

Though he has performed as a magician, he has a very different day job.  He's a psychologist.  In fact, he's a professor of Public Understanding of Psychology at the University of Hertfordshire. He's written numerous books on the subject, including The Luck Factor and Quirkology.

This is a little different from most, which focus on one trick only.  This is a series of little folderol, which he called "10 new bets that you will always win," particularly appropriate the next time you're in a bar.
