A fire extinguishing and fire retarding method is provided comprising the step of confining a fire extinguishing and fire retarding agent in slurry, liquid or gaseous form within a shell wherein the shell comprises such an agent in solid form. An agent such as ice water, or liquid carbon dioxide is useful when employing the shell as “non-lethal” device. The solid shell is sublimable and will burst upon impact or upon exposure to the environmental conditions at the target site to release the contents of the shell as well as the fragments of the shell onto the target site.
