This pirate ship is made from a plastic oil bottle (1lt). With a chisel I cut the shape I wanted (raised on both ends and lower on the center deck). I turned the cut piece upside down and glued it to the boat as a base/deck. Then I used corks and wooden straws for the masts, painted it with acrylic paints and to finish it off I put used color traps for the sails and ropes for the ladders/boat ropes.
