Occultatum by Menny Lindenfeld

A participant hides a personal object (e.g. her ring) in one of many boxes. 

She has a real FREE CHOICE to hide the object in any box. 
She can FREELY MIX the boxes as much as she wants. 
You can be blindfolded or even OUT OF THE ROOM during this process. 
And when you come back, you GENUINELY DO NOT KNOW where the object hides. 

And yet, without the use of electronics or magnets, and WITHOUT ASKING THE SPECTATOR ANY QUESTIONS, you are able to guess where the object hides - using the Occultatum™ psychological system. 

You can perform with any number of boxes, or without any boxes at all - by simply letting someone sign an object instead of hiding it. 

You can apply the system for close-up, for stage - using large objects (e.g. a basketball) or fully impromptu - using everyday objects (e.g. disposable coffee cups, beer caps, beer coasters, packets of sugar, and more). 
You can even perform with your own business cards - which is a powerful and a memorable way to hand out your cards. 

The METHOD IS BULLETPROOF and works with 100% accuracy every time.
