Ping pong ball
The players divide into two sides and take their positions at each end of a wooden table about 6 feet long. A ping pong ball (or any light celluloid ball) is placed in the center, and each side tries to blow it off the table at the other end if it goes off the sides it does not count, but is put back in the center again. The game soon develops strong lungs, but needs composure just as much because the best player is the one who can blow without laughing at the faces of those opposite him as they blow. It is best to play kneeling or sitting round the table. A more complicated way for five players a side is to have a goal at each end marked on the table; then each side has a goalkeeper, two forwards, stationed at the other end to blow into the enemy's goal, and two backs to pass the ball to their forwards.
