The Secret of Invisibility
"Walk UNSEEN among people or CROWDS," promises this website, "The secret of invisibility... REVEALED." This is not a toy or a magic trick, boasts the advertisenment, nor is it an illusion or a ninja technique. You (yes, you!) really can walk sight unseen into your neighborhood bank vault, through the girl's locker room, or out the back door at your family reunion. This is the secret of the gods! And to access this 1,000 year old secret, all you have to do is... spend $30 on publisher Bill W. Williams' book. But don't worry - you'll make back the $30 in no time, plus much, much more, robbing the collection plate at church or selling videos to "Girls Gone Wild!"
