Have you ever seen a windsock blowing in the wind? Well, you can make one of your own! This is a fun
game that you can do with things you may have at home. You just need to follow a few easy steps.

You will need:
    ●one piece of colored paper
    ●five ribbons
    ●strong tape
    ●a string
    ●a pencil

What to do:
     Step 1: Decorate the paper. You can draw pictures on it. You can write your name. Do anything that will
make it special to you.
     Step 2: Roll the paper into the shape of a tube. Then stick the tube together at each end and in the middle
with a strong tape.
     Step 3: Use a pencil to make a hole into both sides of the tube. The holes should be only on one end of the
tube. Pull the string through both holes. Then tie the ends of the string together.
     Step 4: Make five holes around the top of the other end of the tube. Put a ribbon through each of the holes.
Tie firmly in case they get loose.
     Now your windsock is ready to use, but how does it work? Wind flows through the tube and makes it fly
and dance around. Hold the windsock up in the air by its string and run around. It will fly behind you. You can
also hang it outside and watch it dance around on its own!
