Spy IDs and Secret Messages

PD Day Activity

For Families

About the Activity

Become a secret agent for the day! Create your very own Secret Agent ID card, complete with a fingerprint you’ll take yourself. Then make a red‑lens viewer and learn how to write hidden messages that can only be revealed using your custom decoder.

This self‑guided activity is available at all library locations throughout the PD Day - stop by anytime, get creative, and unlock your inner spy!

This activity will be available at all library locations on Friday, May 29.
