MAKE A WINDSOCK
Cut one sleeve off an old long-sleeved shirt.
Bend the wire into a circle. Make sure it is the same size as the top of the sleeve.
Place the wire into the top end of the sleeve. Take the needle and thread and stitch it, so the wire will stay in place.
You have just now made the mouth of the wind sock.
Now, place the rock in some cloth on one edge of the wire. Sew it on tight to hold it in place.
Tie the string onto the wire opposite the rock.
Tie the other end of the string to a branch where it can move freely. The rock will keep the windsock facing into the wind.
Now, your windsock is working! Use a compass to find out which direction the wind is blowing from.
