This is a new type of fire extinguisher. It does not put out fires in the normal way, but instead uses a fire-extinguishing ball contained within it. The shell of this fire-extinguishing ball is made from a special material which is elastic, with fire-extinguishing material inside. When you throw the fire-extinguishing ball into the fire, the shell will burst due to the high temperature, and then the fire can be extinguished using the materials inside. In addition, the fire extinguisher also contains an oxygen tank, which can prevent the inhalation of toxic gases during a fire.
