The ninja are said to have been capable of remembering extensive details about the estates and castles they infiltrated. To learn how they were able to recall large amounts of information without taking notes, we take a look at some of the mnemonic devices mentioned in ninja documents. In the latter half of the program, we examine torches developed by the ninja. With the help of a pyrotechnician, we recreate a Mizukakyo, or water-resistant torch, using ingredients of the time. Join us to see the experiment results!
