Hide secrets in plain sight with invisible inks, codes, cyphers, and disguises with this “noteworthy” secret message kit for two! The second installation in SmartLab’s hilarious, retro Spy School series, Spy School – Secret Ciphers includes two fully equipped secret message cases for spies in training. Each case contains everything two kids need to keep their secret messages top secret, including UV ink pens, UV lights, red filters, codes wheels, and more. From secret codes to secret folds, this kit has more than 30 undercover ways to write and send messages—even when people are watching! Learn and practice real-world codes such as Caesar’s Cipher, the Dancing Man, Pigpen Code, Moon Code, and Zig Zag. Practice hand signals and use message masks to thwart “enemy” agents. Learn the science behind invisible inks, light waves, acids and bases, and fluorescence. There’s so much to cover, you may need a clandestine meeting to test your skills!
