Showing ten cards shown to your audience and ask a spectator to choose one. The cards are shuffled and lined up face down on the table. Now show a small machine and ask the spectator to slide freely along the line of cards. All of a sudden the machine will stop in front of a card. The card is turned over and turns out to be the selected card by the spectator!

This amazing effect was created by Dick Koornwinder, a great magician who won the prize at the FISM World Championships of Magic. Magicians from all over the world consider this effect, unique, a masterpiece of magic.

The Tenyo has graced this classic of magic, creating a brand new machine able to flow freely, and even more surprisingly, the machine can be examined by the spectators.
