Americans were not interested in it at first, 1 The game was then played across dining-room tables, or
on the floor with the net strung (用绳缚) between two chairs.
2 The bats were made of wood. 3 The game then quickly spread all over the world. An

ball, and "pong" was the sound of the ball when it hit the table.
