All it takes is a feather for each child to get this even under way -- or airborne. (You can buy a package of feathers at many department stores or hobby shops.) On cue, players try to blow their feathers overhead. Whoever keeps theirs aloft the longest without using her hands is the winner. For a team challenge, kids can pair up and face each other from a distance of 3 feet, then try to volley a feather between them.
