Human: I'm interested in a new sport called sand volleyball. Can you tell me more about it? Assistant: 
Sand volleyball is a variation of volleyball played on sand courts, which are typically smaller than regular volleyball courts and have a higher sand content. The game is similar to traditional volleyball with the main difference being that players must use their feet to pass the ball instead of their hands. Players can also dig up the sand during play, which can be used as a defensive tactic or offensive weapon.
