Rabbits' Magic Pocket
Predict 4 of a kind
Note
We will use the 8s in this example, but you can use whatever you want.
Setup
Take out all the 8 from a 52 cards deck. With the deck facing up, place an 8 at the bottom. Next take out 7 cards from the top, and place two 8 there. Finally, put the last 8 at random in the deck.
Start by making a prediction and take out the random 8 to deal it face-down on the table.
Next, with the deck facing-up, deal cards on the table. Once you saw the two 8, say to the spectator that he can say "stop" whenever they want to cut the deck.
Next, put both piles face-down. Ask the spectator which pile they want to look, to give them a sense of control, but in every case, turn the top card of the deck.
Because it is an 8, take the cutted packet face-down and deal 8 cards. Flip the top cards of the 2 new created packets.
You can finally reveal your prediction, which is the final 8.
