Author's blurb:

Demonstrational hypnosis is a necessary skill for all hypnotists. It doesn’t matter if you are a hypnotherapist who is speaking before groups to build your client base or if you are a stage hypnotist or even a street hypnotist. You need to hypnotize people in front of audiences and you need your inductions to work. This book will show you what you need to do to make those demonstrations successful.
Skill in choosing motivated, cooperative, and excited volunteers is not just for hypnotists. Magicians, mentalists, and motivational speakers will also find these concepts extremely useful.
