This video starts off with a neat optical illusion that he uses to demonstrate the effectiveness of force card tricks. He shows a piece of paper with "Paris in the the spring" written on it, most people's mind will skip over the second "the" and will read it, "Paris in the spring." He then goes on to demonstrate a shuffling trick that allows you keep a hold of a given card while shuffling. Finally the presenter explains the difference between asking someone to "Pick a card" and asking someone to "Touch a card."
