Simple model boats can be made with kits or items from around the home. Create a miniature of a standard boat design with paper and cling film, or create a new design. Make a pirate ship, sailboat or puddle boat in one afternoon. Follow these directions for an easy model pirate ship that can be sailed in a bathtub or local pond.
Close the half-gallon milk carton and seal the open end shut with glue. Set aside to dry. Measure up two inches from the bottom of the half-pint milk carton and cut the bottom section off. Paint the outside of this section brown and set it aside to dry. Paint the half-gallon milk carton brown and set it aside to dry.
Lay the half-gallon milk carton on its side after the paint has dried. This is the body of the ship. Place the half-pint milk carton on top and centre it on the ship's body. This is the 'captain's cabin' portion of the pirate ship. Glue the small carton in place. Draw on details such as windows, doors or portholes with the black marker. Paint the portholes yellow.
Cut the sides from the remains of the small milk carton. Choose one of the four rectangles this creates to cut in half. These will be the 'small' sails for the ship. Cut two holes one-quarter inch from the top and bottom of two of the large squares. Bend the square slightly and insert a straw. Each straw is a mast, and the squares will be the sails. Repeat the process for the two small squares, and insert the straw into the holes.
Roll the clay into two small balls, each approximately the size of a large marble. Press each clay ball on the top of the captain's cabin and insert the straws with the sails. The large sail should be on the bottom. Glue in place if necessary.
