fire extinguisher ball

A fire extinguisher ball is a device that can automatically activate and suppress a fire when thrown or rolled into the flames. It consists of a spherical shell filled with a dry chemical powder that is released when the ball bursts due to the heat. The powder can smother the fire and prevent it from spreading. Fire extinguisher balls are designed to be easy to use, portable and effective for small fires in homes, offices, vehicles and other places.
