A Head Full of Books by Mark Elsdon
A Head Full of Books has actually replaced the Hoy book test as my go-to casual mind-reading effect.
Whilst visiting someone's home (or in a bar or coffee shop that has books on the shelves) you ask someone to select any book from their library or off the shelf. He opens the book to any page and reads the first few lines to himself while you look away.
Without touching the book you immediately reveal what he just read! It's that clean.

• Zero memory work.
• Use almost any book, in any language.
• Nothing is written down by the participant or the performer.
• No sleights, finger breaks or other moves.
• No forcing - it really is a randomly selected book and a freely selected page.
• No maths, calculations, apps or other unnecessary process.

[Note: To perform this you will need a PK ring and a small magnet. The best ring to use is specified by Mark and he provides links to where you can purchase these.]

"Seriously this is a steal... Looks exactly as explained above, once again brilliant thinking from Mark. Nuff said." - Michael Clark
"Purchased this and already read it through. This is brilliant thinking from Mark and this is definitely something I will use." - Daniel Thomsen
