Stretch a piece of colored string across the room. The object is the
same as in volley ball, that is, to keep the balloon off the floor on
your own side and make it touch the floor on your opponents’ side. Use
either one or two balloons, depending upon the number of players. Of
course use only the simplest rules of volley ball, thus making the game
suitable to play in the average room. Each player on the winning side
gets a balloon.
