Here is The voice of the unconscious for those who love inexplicable books:
You give a book to a viewer, asking them to open the book on any page. The book is a normal book.
The spectator chooses a word, short or long whatever.
You give him a small card or a sheet of white paper. The spectator writes his word on it so as not to change it any more. Until then, he can change the word as many times as he wants.
You put this box back in the book, of course without looking at the word and leave the book on the table.
And now you focus …
You announce the chosen word, take the box out of the book. The written word exactly matches your prediction.
The tour can be done alone
To choose and write the word, the spectator can be several meters from you. Or you can turn around.
