VINDALOO, WITH A NOD TO PAUL CURRY'S "OPEN PREDICTION" THIS HAS TO BE THE ULTIMATE SOLUTION ! USE YOUR OWN DECK OF BICYCLE CARDS...YOU MAKE AN "OPEN PREDICTION" LETTING EVERYONE ACTUALLY SEE WHAT YOU WRITE...A DECK OF SHUFFLED CARDS ARE SPREAD FIRST FACE UP, THEN FACE DOWN, ANY SPECTATOR POINTS TO ANY CARD, THIS IS THEN PLACED FACE DOWN IN THE CENTRE OF THE DECK, WHILST YOU OPENLY AND CLEANLY SHOW THE REST OF THE DECK, THEY ARE INDEED, ALL DIFFERENT...WHEN YOU FINALLY SPREAD THE ENTIRE DECK FACE DOWN, THERE IS OF COURSE ONLY ONE CARD FACE UP, THIS PROVES TO BE THE VERY ONE YOU OPENLY PREDICTED !!! THIS IS INCREDIBLE, A MUST FOR ANY "WORKER", VERY, VERY EASY TO DO, IN FACT IT'S 100% SELF WORKING !
