We spent a few hours today building a telegraph with another family. It is amazing what you can do with some old Christmas lights, wire scraps, cardboard, aluminum pie pan, duct tape, a battery, a paperclip, and a buzzer from Radio Shack. It was a good first effort, worked great...next try will be longer wire so we can send messages from room to room instead of across the table.
