A simple method, but a most baffling effect!
Three cards are shown with different geometric designs: A red Cross, a green Triangle and a blue Square. A spectator selects one (free selection, no force whatsoever) and you show you have predicted it! No sleights, no moves, this is an easy trick that you will enjoy performing. Keeping it in your pocket and you will never stop doing it.
It comes complete with laminated cards.
