I have done a couple of recent posts on code and cipher breaking, SIGINT on signals intelligence and A Crypto Problem about Edgar Alan Poe's The Gold-Bug.And so I thought what better science kit for this week than Spy Science,which has materials for sending secret messages a number of different ways including codes, invisible ink, a cypher wheel, encryption sheets, and a Spy International ID card. And if you are found with the secret spy ID card I'm afraid it will give the whole game away. But no matter. Kids will no doubt love being an official secret spy.

You can read more about Yardley in the book The Reader of Gentlemen's Mail: Herbert O. Yardley and the Birth of American Codebreakingby David Kahn.

The same tactics used by CIA and KGB agents can also be used in less serious situations-and these techniques can work in surprising ways. Planning a surprise birthday party for someone special?
