（3）In America，there is a new sport called"earthball"．"Earthball"，which is like a huge beach ball，was thought of by Stuart Frand．The idea of the game is to keep the ball in the air for as long as possible．As the ball is very big，lots of people have to play together．There are no winners or losers in the game，the idea is simply to enjoy yourself as much as you can．
"Earthball"is just one of the games in a "New Games Festival"．It took place in the country near San Francisco，in the USA．
Perhaps other countries can follow the example of the Californians and have festivals to test new games．
