Sepak takraw is a very popular sport in Asia and is growing rapidly. Each team has three of a five-foot high net. Each team tries to send the ball back over the net to the other team. Players can use their feet knees backs shoulders or heads but they can't use their hands or arms. Like in volleyball there are passes and sets and the two games are very similar. The takraw ball is made of plastic or of rattan (a material like bamboo)and it weighs 170 to 190 grams.
