You Know is a powerful prediction effect that is so direct, so fair and so utterly baffling. It uses an ancient, underused principle that has been dusted off and modernized with new twists to create a stunning hands-off prediction.
So what's the effect? You briefly show an envelope in your front pocket and mention that it will be important a bit later. A pack of UNO cards is now introduced and a participant names any of the four colors in the game to be their target color. They take the cards and genuinely shuffle them into a truly random order. They now look through the shuffled pack and remove the first three cards of their target color that they come to. The numbers on these cards are added together to arrive at a sum. The envelope is now removed from your pocket and turned around to show one number was written on it - the sum of the three numbers! Even more impressive, inside the envelope is a prediction of the SPECIFIC COLOR they named and the EXACT THREE NUMBERS they arrived at!
