ok, you take a stack of cads, remove the top card form the stack and show your friends the card under it, but dont look at it yourself.
then, you put the top card back it its place, but while no one notices, you should look at that top card and remember it.
Then, you shuffle the cards, but you have to make sure that the top cards ( which you secretly memorized) and the card that you don't know that you showed your friends don't separate.
Then, after you have shuffled the cards, you start putting the cards one by one, saying that all these cards aren't the one that you showed your Friends before. And when you will finally reach the card taht you removed form the top, the one that you had to remember, th card right after it will be the card that you showed your Friends and told them to remember.
