there is a commercial on the natural geographic channel that can read your mind. the show it is advertising for is called brain games. so its a commercial with 5 cards, all are different. you stare at your card and memorize it. the cards leave and then they tell you to stare at a rubber ducks head. then they bring the cards back and ask, has your card disapeered. AND ITS GONE! ive seen this commercial at least 3 times and i answered differently each time. CHECK IT OUT!
the cards are not the same.... for example, the card they give you is 6(hearts) 3(diamond) J ( spades) K ( clubs) 10 (hearts) When the cards reapear they are: 6 (diamond) 3(hearts) j (clubs) king (spades) They remove 1 card and all the other cards are different enough for you to not notice on a quick glence.
