Spy Labs: Secret Message Tools - Thames & Kosmos Eric Carle Plays “Pop Goes the Weasel”As a detective, you need the right equipment for your investigations, including tools for writing and uncovering secret messages. Exchange confidential messages with your fellow agent using disappearing and reappearing ink that only the two of you can read! Using either of the two secret pens, you can write a message that, once dry, becomes invisible. The other pen will not only reveal the information, but you can also use it to send your reply. 8+
