Brain Breach by Ken Dyne

EFFECT:

A number of people are asked to write a single password onto pieces of paper. The papers are collected and one participant is asked to locate his paper from among those handed in, along with a random one belonging to someone else.

Now that he knows both parts of the code he has become the most vulnerable link in the security chain; which you prove by revealing both words.

The plot is fascinating and compelling, the method is dumbfounding and the reaction is mind blowing.

This special release also includes:

The 'Cat Among The Pigeons Principal'.
Ken's thoughts on selecting environmentally suitable material.
