A water gun is a toy designed to shoot water, typically used for recreational play during warm weather. It consists of a plastic body, a trigger mechanism, and a reservoir for holding water. When the trigger is pulled, water is expelled through a nozzle, allowing users to spray water at targets or other players. Water guns come in various sizes and designs, ranging from small, handheld models to larger, more complex versions that can shoot water over long distances. They are popular among children and are often used in outdoor games, such as water fights or summer parties.
