A water balloon is a small, flexible balloon made from rubber or latex that is filled with water. These balloons are typically used for fun activities, such as water balloon fights or games during hot weather. They come in various sizes and colors, making them popular for parties and outdoor events. When filled with water, a water balloon can be thrown at a target or another person, bursting on impact and creating a splash. Safety is important, as the broken pieces can pose a choking hazard or cause slips. Proper disposal of broken balloons helps protect the environment and wildlife.
