Four Jacks Card Trick
This is a simple trick that will amaze your friends and family when you try it on them. You need to take out 4 Jacks and 3 other cards beforehand, and hide the 3 cards behind the Jacks so that it looks like there are only 4 Jacks in your hand to the audience. You then place the cards on top of the deck, so that the 3 other cards are on top, while the audience thinks there are 4 Jacks on top.
Place one of the "Jacks" on the bottom, the next one in the middle, and one near the top. By now the audience will think that 3 of the 4 Jacks are somewhere in the deck, when in reality the 4 Jacks still have yet to come.
Show the "last Jack" (really the first) to the audience, as proof. Then say Abracadabra!, or tap the deck, or something of the equivalent. Magically, the 4 Jacks will rise to the top of the deck.
