This clever mathematical principle allows you to find a thought item among any number of items, even
though you do not know the initial order. You don't even need to know what they are. You
see nothing. It is entirely hands off and improvised, and can even be done over the phone.
It works with any number of flat objects (cards, index or business cards, coasters, etc.) or
usual objects (key, coin, lighter, pen, etc.).
Two practical examples are provided, but it is so easy that you'll be able to improvise your
own mentalism effects with borrowed objects or cards, or with your own business cards and
give them away at the end. It can also be used as a safety net.
