An example fire extinguishing apparatus may include a housing comprising at least one escape hole, a first compartment within the housing containing a first extinguishant agent, and a second compartment within the housing containing a second extinguishant agent. The first compartment may be rotatable relative to the second compartment. The apparatus may further include a barrier disposed between the first compartment and the second compartment configured to separate the first extinguishant agent from the second extinguishant agent, and a barrier rupture mechanism. The barrier rupture mechanism may be configured to rupture the barrier in response to rotation of the first compartment relative to the second compartment to permit the first extinguishant agent to mix with the second extinguishant agent and cause a pressure generating reaction that forms an extinguishant mixture and forces the extinguishant mixture through the at least one escape hole of the housing.
