IT’S A MIND BOGGLER! MIND BUSTER! MIND BENDER! YOU NAME IT, THIS IS IT!
You show two packets of cards containing red-backed and blue-backed cards (all with blank faces). Two spectators each lay out pairs of cards from the two freely shuffled packets. Despite any constraints, you have accurately predicted the outcome: ONLY THREE PAIRS WILL MATCH and THE THREE PAIRS WILL BE RED! At no time do you touch the cards as the spectators make their choices.
