idk if your familiar with any of the tricks in royal road? theres one where you have a spectator pick a random card and without him or anyone looking at it put it face down on the table. a second spectator then divides the rest of the deck into three piles, chooses one of the piles, counts how many cards are in that pile then puts the pile in there pocket. the first spectator then flips there card, and whatever number is on that card you make that many more cards appear in there pocket. i've gotten some pretty surprised reactions from my friends. i'll make a video for that. i have a variation i made up myself of it 2.
