response: I see, the rackets are strung with cord, does that make them heavy?
original_response: I'm sorry. I didn't think they were that heavy. A racket is just strung with cord.
history: i always wanted to learn how to play tennis when i was a kid Interesting, did you want to play singles or doubles with a teammate? It didn't matter, but when I was a kid I was pretty skinny and weak and that racket was so heavy I could barely hold it.
knowledge: Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court.
