The Sentir Tear by David Numen

David Numen describes his thoughtfully engineered center tear variation. He uses many photos to communicate the subtleties clearly.

As an application for his center tear David describes a Living and Dead Test.

And as a bonus he teaches you a wonderful book test. In terms of what the audience will see and recall this is pretty much similar to the Canasta Book Test in effect but quite different in method. A page number and a line number are chosen freely by two spectators - both choices unknown to the performer. A third spectator is asked to select a book (or they could bring their own) and to look up that page and line and someone else selects a position on that line. You reveal the word - and can also reveal the entire line should you wish.
