Imagine this: the magician hands you a pack of cards which you examine and find to be quite ordinary. You are invited to select ANY 5 cards either randomly or by choice. The 5 cards are handed to the magician - he looks through them carefully - he places one card on the table face down and returns the other 4 to you. You enter the 4 cards into the computer, press 
and watch amazed as the computer tells you what the face down card is.
At no time does the magician touch the computer.
If you would like a demo you could tell me your 5 cards by e-mail. But not only is this a piece of fascinating magic - it also makes a great puzzle. It took me many hours to figure out how the trick works - I encourage you to do the same then you can be the magician! |
