Spycraft: Ciphers and Codes

An after-school workshop for ages 9 to 13 that turns code-breaking into a hands-on craft. Participants learn classic ciphers — from Caesar to Pigpen — and get a recipe for homemade invisible ink, with time to encode their own messages. It meets Wednesday, November 18, from 4:30 to 5:30 PM at the Austin branch. Registration details are not listed, so calling ahead to confirm availability is wise.
