Dunagan's Boat

Dunagan built a boat today to test the effects of a rudder.  He used a foam meat tray, a cup from an egg carton (& hot glue), a rudder from a milk carton (waterproof cardboard), a twig mast and a construction paper sail.  He had three separate slots for the rudder, and when he blew the sail, he could see which direction the rudder would steer.
