FROM a one-way pack which has been thoroughly shuffled fan off five cards in the right hand, turn the rest of the cards face down and hold the pack with its outer end pointing to the right. Hold the fanned five cards with their faces towards a spectator and ask him to mentally select just one card. This done, turn the fan face downwards and insert the cards one by one in different parts of the pack. The action has reversed the five cards. Hand the pack to the spectator for another shuffle. Take the pack back and holding it in your left hand run cards from the top into the right hand counting them as you do so. Watch for a reversed card and as soon as one appears, run several more cards, lift off the packet, fan the cards, noting the bottom card of the fan, hold them faces towards the spectator and ask him to say whether his card is amongst them. If it is not drop the packet face down on the table and take. off another fan repeating exactly the same actions. When the spectator sees his card, square that fan and drop it on the other cards on the table remembering the number the reversed card occupied in the fan. Finally drop the remainder of the cards from the left hand on top noting the bottom card as you do so. You know just how many cards the chosen card is below the card just sighted so that by fanning the cards towards yourself you can pick it out at once. If there happen to be two reversed cards in the fan, put one on the top and the other on the bottom. Have the thought card named and show top or bottom card as the case may require.
