It seems that Jake and Mitch, Kitzbühel's favourite two Aussie boys, never cease to entertain. The "red card black card" trick looks simple, but leaves you in awe. The way it works is as follows: the trickster deals the entire deck face-down into two piles, and picks a volunteer. Each time that the trickster deals a card, the volunteer says either "red" or "black"; and the card gets accordingly dealt to one of the two piles — the "red" pile, or the "black" pile. Exactly halfway through the deck, the two piles are swapped — i.e. all "red" cards now get dealt to the black pile, and vice versa. Through the entire dealing process, neither the trickster nor the volunteer sees any of the cards: the calling out of "red" or "black" is a completely random choice, decided each time by the volunteer. At the end, the trickster turns over and fans out both piles: and unbelievably, they're both exactly half-red (all together) and half-black! Check out the video.
