Two year ago I wrote about a Cryptex you can buy, but now there is also a detailed instruction on how to make your own Cryptex.
A Cryptex is a kind of lock with a password, that holds a roll of paper. Author Dan Brown said in his “Da Vinci Code”, that Leonardo da Vinci invented it, to let messengers carry secret papyrus rolls that the messengers themselves may not read; only the sender and the recipient know the password. If the messenger would smash the cryptex to read the message, a vial containing vinegar which was rolled inside of the papyrus roll would also break even earlier than the cryptex itself, the vinegar would spread over the message, disolve the ink, making it unreadable.
