I was really excited for this. I love the razor blade swallowing illusion so I was hoping this would
be great. Nope. i don't know that they even practiced this in material in front of real audiences.
Some of it is impractical. Most of it is unimpressive. Rather then get this buy the book Helter
Shelter. it is about razor blade swallowing and is great. it is also available from Penguin.
