Making a homemade sail boat is a simple craft to complete with children that not only creates a toy to be played with, but serves as an enjoyable craft for the child while you and he are working on it. A milk carton sail boat uses half of an empty carton as the hull of the boat, with a mast system built using plastic drinking straws and saran wrap. While the construction of the boat can be completed by a child, an adult should always help to cut the carton in half.

Skill level:

Things you need

  • 2L milk carton
  • Permanent marker
  • Ruler
  • Crafting knife or utility knife
  • 3 drinking straws
  • Tape
  • Hole punch
  • Fishing line
  • Scissors

  1. 1

    Draw a line on a 2L milk carton in marker using the ruler, dividing it in half vertically.

  2. 2

    Cut along the line using a crafting knife to create two boat hulls.

  3. 3

    Tape the middle of one straw 1 inch from one end of a second straw, perpendicular to the second straw, then tape the middle of the third straw to the second straw 3 inches from the other end, again perpendicular to the second straw. Use a figure-eight wrap with tape to firmly secure the straws. The second straw is the mast, while the other two straws will support the sail.

  4. 4

    Tape a piece of cling film to both support straws, then trim any excess wrap with scissors.

  5. 5

    Tape the bottom of the mast to the centre of the hull of the boat.

  6. 6

    Punch a hole in each corner of the milk carton hull, 1 inch below the top of the hull.

  7. 7

    Tie a piece of fishing line to one punched hole, then tie the other end of the line to the top of the mast and cut off any excess.

  8. 8

    Repeat for the remaining three holes.
