You Know is a mind-boggling demonstration of mentalism using regular UNO Cards. This powerful prediction effect is so FAIR, so DIRECT and so utterly baffling. David Jonathan has dusted off a long-forgotten and criminally underused principle, and modernized it with delightful new twists to create an unbelievable hands-off prediction that is INCREDIBLY EASY to perform!
The Effect:
After briefly bringing attention to an envelope in your pocket, you introduce a pack of UNO cards. A participant then names one of the four colors in the deck as their target color. They then take all the cards and genuinely shuffle them into a truly random order. Looking through the shuffled deck, they 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 total. You then remove the envelope from your pocket to show one number was written on it, which matches their total!
