You just need a deck of card. Shuffle the cards and fan out the cards, make sure the card is facing you, not the spectator! Then, look at the top 2nd card & the top 4thcard , memorize these 2 cards. For example, you see 8 of Hearts & 3 of Spade. So you must either choose 8 of Spade/3 of Hearts. Pick 1 of the card and put it down on a table. Tell your friends it was your prediction card. (don't let them see it!) Request your friend to speak out loud a number, but not more than 50. Here, your friend may say 15. So, you dealt 15 cards out in 2 deck of cards. Now, before you dealt the cards, lift 2 cards together and put it on your left. Then, double lift again the cards and put on your right. Do this when you start to deal the cards, that's why you got to remember the top 2nd & top 4th cards. After that, deal the cards 1 by 1 ,on the left then on the right.

As a result you are actually not dealing out 15 cards, but 17 cards. now, you should have 2 deck of cards on your table. The cards you memorize are at the
2nd bottom of the deck each. Then, double lift the 2 bottom cards and put it on top of your deck. For example: show them the 8 of Hearts and behind this card was another different card. Put back the 8 of Hearts with the another card back on top of the deck. Show them you put the top card on the bottom deck. They may think the 8 of Hearts is in the bottom deck, but actually the opposite thing happens. So do the same to the other deck.

Now, let the surprise begin. Flip up your prediction card & also flip up the top card on each deck. you've taken 8 of Spade as your prediction card. So, tell your friends that the prediction card was the same number as 8 of Hearts and the same pattern as the 3 of Spade.
