The Divine Water Spray 神水噴筒 of the Bing Lu 兵錄
The above image shows an illustration and description of the Divine Water Spray 神水噴筒, or ‘magic water spray,’ from the Bing Lu 兵錄, an ancient Chinese military compendium. The Bing Lu 兵錄 is a specialised Chinese military text that records specific techniques, weapons, and tactical innovations. Unlike broader strategic treatises, the Bing Lu 兵錄 focuses primarily on particular devices and methods used in warfare, making it a valuable historical source for understanding the technical aspects of ancient Chinese military practices.
The diagram illustrates a bamboo device, segmented and bored through, which was used to store and release a liquid mixture. The text on the right describes the construction, ingredients, and operation of this device. Traditionally, bamboo tubes were used in ancient Chinese weaponry to contain powders, liquids, or combustible materials, which could be released or sprayed to confuse, irritate, or blind an opponent.
This weapon combines elements of chemistry and concealment, typical of Chinese stealth techniques. The mixture of barilla ash, red ochre, cowbane, and silver powder would create an irritating effect, further amplifying the impact of the water spray for distracting or temporarily incapacitating an opponent.
