This Christopher Borer effect
involves two books. One has the title "Everything Women know about Men", the other "Everything Men know about Women". When showing the first book, it is
obvious that the ladies know everything about
the men's lives. But when the other book
is shown, all pages are blank, only the page
numbers are there. Seemingly not that much
knowledge around about women.
A spectator is asked to select and read (briefly)
a page in the first book. He (or she) should
also remember the page number that he selected.
He closes the book, but keeps it in his hand!
After a short journey into his fantasy, the
page inside his book vanishes - the spectator
can check it for himself - his selected page
is now blank. In the other, formerly blank
book, the vanished print appears on the exact
page that the -spectator selected.
This easy to perform routine gives you an
interesting plot, but also a great souvenir
for the spectator if you want to hand out
the book at the end.-
