👉 Russian fluid, also known as Russian fire or Russian steam, is a term used to describe a highly volatile and explosive mixture of water vapor and oxygen that was historically used in incendiary devices, particularly during World War II. This mixture is created by heating water in air until it reaches temperatures above 100°C (212°F), producing a dense, oxygen-rich vapor that can ignite with even a small spark. Its high flammability and ability to spread rapidly make it a dangerous weapon, though its use has largely been discontinued due to its hazardous nature and the development of safer alternatives. The term "Russian fluid" reflects its origins and the historical context in which it was developed and utilized.
