A water cannon is a device that shoots a high-velocity stream of water. Typically, a water cannon can deliver a large volume of water, often over dozens of meters. They are used in firefighting, large vehicle washing, riot control, and mining. Most water cannons fall under the category of a fire monitor.
Cannon recovered from the sea are often extensively damaged from exposure to salt water; electrolytic reduction treatment is required to forestall corrosion. [218] The cannon is then washed in deionized water to remove the electrolyte, and is treated in tannic acid, which prevents further rust and gives the metal a bluish-black colour.
