A windsock is an instrument designed to inform in which direction the wind is blowing. Although it serves a scientific purpose, creating a windsock can be a fun and decorative craft. Construct windsocks from a wide array of materials found at home, such as old clothes, or utilise inexpensive craft materials.
Construct the windsock itself out of loose, lightweight materials. A basic windsock design has a lightweight frame that allows the sock to swivel in the direction of the wind, and extra material designed to catch the wind.
You can affix cloth ribbons to a plastic water bottle to create a basic windsock. Cut the top and bottom from the water bottle so that you are left with an open plastic cylinder. Glue the cloth ribbons to the plastic water bottle so that a foot or two of cloth extends off the end of the bottle. You can also use a tube sock instead of cloth ribbons. Make sure to cut off the toes before attaching the sock to the plastic water bottle.
Alternatively, you can use a wire hanger for the frame, or strips of tissue paper for the sock material.
Create a pole to hang your windsock off of so that it can rotate freely in the wind. If you have a flagpole, or any pole that you can hang a string off of, punch holes through the windsock's plastic frame and attach it to the flagpole string with yarn. Alternatively, you can use a wooden dowel. Punch holes through the plastic bottle frame and thread the bottle through the dowel. Don't punch the holes too large or the windsock will not stay suspended on the dowel properly.
If you create a windsock with a wire frame, you will need to suspend it in air by hanging it from a higher structure. Find a branch, or other overhanging fixture, that the windsock can freely hang from. Tie the wire frame to the fixture with yarn.
Make a compass for your windsock. A compass will allow you to quickly reference what direction the windsock is blowing toward. Use an actual compass to calibrate your windsock compass so that all directions are accurate.
For windsock poles created from a wooden dowel, use two straws, some construction paper, glue and a thumbtack to create the compass. Create four construction paper squares, and write a compass direction on each. Glue them to the ends of the straws so that you have a north-south straw and an east-west straw. Use the thumbtack to secure both straws in a perpendicular fashion atop the wooden dowel.
Use heavier, more durable materials to construct a compass for a flagpole. Use wooden dowels for directional arrows and affix with duct tape, or an industrial adhesive if you wish to make the compass permanent.
