For a pack meeting preopening activity, disassemble some familiar device of appliance such as a mechanical alarm clock, lock, small electric motor, or ancient computer. Put various internal parts in four or five open boxes. In a closed box, or behind a screen, have the chassis or shell of the device. Players are asked to look only into the open boxes and guess what the device is. Reveal the correct answer as an icebreaker after the pack meeting opening.
