Spy ID Badge: Each child selected a piece of paper from two containers in order to find out their spy name. One container had spy-sounding adjectives (red, sneaky, silent, etc.) and the other had cool sounding nouns (cobra, thunder, tiger, etc.). The combinations they pulled were hilarious and the kids were really excited about their spy names. We then took a picture of each kid making a spy face (usually a scowl). We had ID badges with a space for their real and code names, thumbprint, and photo. We printed out their pictures and then used tape to "laminate" the whole thing.
Disguise Station: We printed out these very cool disguise kits on cardstock. It was fun to see how many kids, girls and boys, walked around with mustaches the rest of the day. We also put out scratch-art glasses and fake beards.
