# Orden en el universo!

**Select 9 consecutive cards of your favorite suit, e.g., the diamonds from ace to 9, and present this well-ordered set to the audience. Some card tricks using math. **

*by Ehrhard Behrends*

Select 9 consecutive cards of your favorite suit, e.g., the diamonds from ace to 9, and present this well-ordered set to the audience.

The cards are turned face-down and put together to form a little pile. Now three times the following happens:

* The magician deals the cards out: left-right-left-right-…, and a spectator can decide whether the left or the right pile is put on on top. Afterwards the deck is cut at an arbitrarily chosen position.

It is crucial that this is done three times.

Because of the numerous random decision the audience is convinced that the deck is in a rather chaotic state. But, surprisingly, the order is essentially restored. The cards are in the same cyclic order as before.

There are two possibilities to arrive at the starting position:

* The magician has made a secret sign on the back of the ace so that everything is as in the beginning after an additional cut.

* By a secret glimpse at the bottom card he learns the value of the bottom card (in the picture it is a three). He moves exactly this number of cards one by one from the bottom to the top.

Then the cards are presented face-up: big surprise, they are in the original order.

(One can omit the final step if one deals the cards out in a circle in such a way that the ace is the upmost card in this circle. This is easily possible since one knows that the order is cyclic.)

Note: I found this trick in the very recommendable book by Pedro Alegría: “Magia por principios”.
