To communicate in secret with his twin brother, Zeke Moorie, the sleuth of "Betrayed!", uses a "scytale." (This word rhymes with Italy.) A scytale was first used by ancient leaders to send codes during times of war. Here's how you can make your own at home:
1) Find two cylinder-shaped rods that are the same size. (Two thick pencils will do.) Give one of the rods to a friend.
2) Wrap a long thin piece of paper around your clinder, so that the paper runs around the object from top to bottom.
3) Write a message across the paper.
4) Unravel the paper. Your message will now make no sense. It can only be read when wound around a cylinder the same size as yours.
5) Deliver the strip of paper to your friend, who will wrap it around his cylinder. The message can now be read!
