A water balloon fight is a fun outdoor activity where participants throw filled water balloons at each other. These balloons are typically made of thin rubber and can hold a small amount of water. The goal is to splash opponents while avoiding getting wet oneself. Participants often divide into teams or play individually, and the fight can take place in backyards, parks, or at the beach. Safety is important, so players should be cautious of slippery surfaces and ensure that the area is free of obstacles. After the fight, it's common to clean up any broken balloon pieces to protect the environment.
