Blowing balloons is an interesting game. You may have some ideas of it. It is of great value to your health, especially to those who are fat. People usually make an airless balloon halfairfilled, put it on the hand, then blow it hard. Shortly after it flies up, his partner blows it away towards the opposite party. And the opposite blows it back. Repeat doing so until the balloon drops onto the follr. Any party onto whose floor the balloon drops will be the loser. So any party who tries to control the balloon's direction and blows it with great efforts will make the balloon fly straight to the other party and will have more opportunities to win.
