Probably the most simple mental feat ever devised, yet incredibly decptive! Three cards, each with a large coloured spot on, are placed on the table. The Magician has predicted one of the cards and that card is the one the spectator is going to freely choose . The spectator simply names a colour, it's a free choice, no force whatsoever, yet when the Magician's prediction is read out loud by the spectator - it's seen to be the correct chosen colour.
