Wind Socks: Cover a toilet paper cylinder with streamers by gluing the streamers along one end of the cylinder and extending them down the length of the cylinder so that they trail off the other end. When the cylinder is covered, use a hole punch to make two holes at the top of the cylinder equidistant from each other. Run a 10" string through the holes and tie the ends together. Hang the cylinder in a tree and let it hang freely. It will show the direction of the wind.
