The Unsticker: The World Famous Interactive Problem Solver 2nd edition

The Unsticker is a tool for creative problem solving. You can use it by yourself, with your friends and family or in a group problem solving session at work. There are over 300 questions which, when asked randomly, will loosen and untangle even the stickiest of problems. Most people report that after 4 or 5 questions, either their perspective of the problem has changed dramatically, or the problem seems to be 'solved' altogether. And if that wasn't enough, using The Unsticker is fun!
