The fire extinguishing ball includes an outer ball cage, an inner ball cage freely rotatable within the outer ball cage about one axis, and an internal fire extinguishing assembly carried by the inner ball cage and freely rotatable therein about a different axis. The internal fire extinguishing assembly includes a hollow ball-shaped body containing compressed gas and fire extinguishing agents. A valve assembly attached to the top of the body permits refilling of the body and dispersion of the contents during operation. The internal fire extinguishing assembly is connected to the inner ball cage so that the valve assembly will be disposed on top when the fire extinguishing ball is at rest. The ball can be tossed or rolled towards fires in difficult to reach areas. Exposure to heat opens the valve in the valve assembly to thereby disperse the contents of the body and extinguish the flames.
