Brilliant wasn't it!! :-)
I've read a few books on hypnosis, and it seems to be that he is a master of subtle suggestion. He carefully phrases his sentences and taking in such a way as to relax you... What we, as the viewer, don't see is the prep work that he does, it's editied out. But he will probably spend quite a while talking to his subject(s) relaxing them and placing ideas in their heads.
