Well... I don't know how Criss Angel does it, but one day I was watching a TV program that is being presented by a woman. On that day she had a guest who was a professional hypnotizer. So, this man said that he would petrify her and told her to lie on 2 chairs and a table. She lied on the table while her feet and head were on the chairs. Then he hypnotized her and removed the table... I was astounded!!! She remained at the same position!!!The best part was that when he removed the table he told a woman from the audience to stand on her tammy! The hypnotized woman didn't bend at all and remained in the same position... I don't know how he did it...
When he woke her up she didn't remember anything...
By the way the hypnotizer and the man were not speaking the same language. A woman were translating all he was saying...
If someone knows more about this kind of hypnosis ("petrification") and wants to share his/her knowledge please feel free to add a comment!
