Hi !

Somebody from the forum pointed to the book Mathematics Magic And Mystery" by Gardrner, for a prediction trick, but I have discovered so many good things in the book ! It is impressive !

the Guergonne trick is baffling : you show half of a deck, ask a spectator for a number and asks to mentally select one of the card, you shuffle, cut, and then after dealing the cards on the table a few times, you count the number, and reveal the card .. you don't even have to know the card .. and it's self working (just need to pay attention and memorize a few stuff)

There are MANY excellent tricks in the book !!

the book is 9$, so I see no reason why you don't own it yet !!!
