You can make a private telephone line with some string and two empty tins. Firstly, cut off the tops of the cans and punch a small hole in the bottom of them. Next, thread the ends of the string through the holes and tie a knot inside each can. Lastly, go away from each other and talk to your friend. Each person should hold one can each.
