A type of [[toy gun]] that is designed to shoot water, though other liquids are occasionally also used in them.  Most are shaped like a [[gun]], but other shapes exist as well (such as tube or hose shape). Furthermore while most water guns have a reservoir of water for multiple shots, some designs can only fire once before needing to be refilled.
