Black smoke is an extremely toxic gas used by the Martians launched from the Tripods as well as the Flying-machines.

DescriptionEdit

Physical PropertiesEdit

The Black Smoke is reportedly deadly enough that any living organism that touched it would be killed almost instantaneously; in the 1938 radio play, it said that even gas masks could not prevent the gas from killing the wearer. The Black Smoke is truly more of an aerosol as it is dense and sinks to the ground (meaning that one could climb to a high place and survive) and that as it clears, it leaves behind a black, powdery residue that is cleared away by Martians with jets of hot steam.

According to the films, the Black Smoke is an unknown element which mixes with argon in the atmosphere (based on spectrometer readings) to reach its poisonous state. However, this is unlikely as argon is a noble gases, meaning it is very stable and inert and only bonds with other elements under extreme conditions.

DeploymentEdit

The Black Smoke is stored in special canisters and fired by a cylinder-shaped device, both of which are carried in the tentacles of the Tripods as separate objects. As these launching cylinders are held separately, it has been suggested that some other device was intended to use the cylinders and they were brought out in a makeshift fashion by the Tripods. The cylinder launchers launch the canisters of the Black Smoke in such a way that it produces no smoke (other than the Black Smoke itself, of course); compressed air and electromagnets have been suggested as the propulsive device. The canisters also do not explode when they hit the ground, but rather shatter, and the smoke inside billows out. The described size of the clouds of the Smoke strongly suggests that the smoke within the canisters is highly compressed.

A few lines during the battle with the Thunder-Child suggests that the flying machine also was capable of deploying Black Smoke, but whether this is done through cylinders or by spraying it out is unknown.

The Martian fighting machines are described as normally dispersing the black smoke by spraying jets of heated water at them while wading through the cloud, so that we can be fairly certain the gas is either harmless to Martians, or the clouds are lower than 100 feet. Earlier notes by H.G. Wells indicate that he had originally intended the cylinder launching devices to be capable of firing cylinders that would disperse water to clear away black smoke clouds.

Description by the Martian Technology ReportEdit

The Martian Technology Report states that The Black Smoke, used to such terrible effect against the population of London, is more accurately described as an extremely fine dust or powder. It is quite substantially heavier than air, and when released tends to stay in a dense, hill-shaped cloud which slowly flattens and spreads across the ground.

The Smoke is insoluble in water; instead it forms a layer of scum on the surface which sinks slowly to the bottom, making way for more. It appears that the Smoke undergoes some chemical reaction upon

contact with moisture which renders it inert, as it is quite possible to drink without harm water which has had the scum strained from it. Similarly, moisture in the air causes the microscopic particles of dust to slowly group together into larger particles, and sink gently to the ground.

Despite a degree of knowledge concerning the behaviour and effects of the Black Smoke, little is known of its chemical composition, and scientists are still not entirely certain of precisely how it has its effect. Spectrum analysis of the black powder points unmistakably to the presence of an unknown element with a brilliant group of three lines in the green, and it is possible that it combines with argon to form a compound which acts at once with deadly effect upon some constituent in the blood, causing it to near-instantly coagulate. Its behaviour when exposed to moisture only serves to enhance its lethal properties; as it is inhaled by its victims, it is believed to undergo a reaction with the natural moisture present in the lungs. This causes it to coat the internal surface of the lungs with a smothering layer of powder, preventing the victim from obtaining vital oxygen from the air. The only ways to avoid its effects are to move to a sufficiently elevated position that one is above the level of the cloud, or to filter the air one breathes through a moistened cloth of fine weave.

In Other MediaEdit

The Black smoke is rarely depicted in other media, and when it is, it is only on unusual occasions. Black Smoke was mentioned in the Orson Welles radio broadcast, where two soldiers were firing at a fighting machine. They donned gas masks, but continued to cough, and died after some time. This would be in keeping with a blood agent type of chemical gas, but not with nerve agents, or skin irritants. Black Smoke also features in a number of comic book versions, where it often dissolves the flesh off of human bodies. Often roleplaying games will mention black smoke, but often suggest that it can be filtered through a gas mask made of a cloth soaked in water, or one may hold their breath and outrun the cloud.
