Stop by any Pike County library branch and pick up a Kentucky Science Center Sleuth Kit!
This kit allows kids to combine their imagination with STEAM skills needed to become would-be investigators. The kits hone skills of observation, investigation and analysis to expose hidden messages, analyze fingerprints and encode messages. Materials and instructions are included to experiment with Hidden Ink, Fingerprinting, and a Cipher.
