The act of dousing consists of simply filling a bucket with flammable liquid (gasoline, kerosene, etc.), throwing it at a zombie or zombies, lighting a match, and running. If there is room for escape and no danger of residual fire damage, the only drawback to this method is the close proximity required to fully drench the enemy.
The common torch, which consists of a propane tank attached to a nozzle, has neither the heating power nor the fuel supply to burn through a zombie skull. But it can be a convenient firestarter if the undead in question have already been soaked in a flammable liquid.
This device, perhaps more than any other, strikes people as the ultimate zombie eliminator. A jet of flame, two hundred feet long, composed of jellied gasoline, can turn an undead crowd into a wailing funeral pyre. So why not acquire one? Why not forsake all other weapons for this man-made fire-breathing dragon? The answers are as realistic as they are numerous. The flamethrower was developed purely as a military weapon and is no longer in service with the U.S. Army and Marine Corps. It would be difficult to find any model, let alone one that works properly. Acquiring the fuel is even more difficult than the thrower. But assuming you can find both, you must consider its practical use. Why carry seventy pounds of equipment on your back when only a handful of ghouls are loose? A flamethrower’s weight makes it a liability if you are on the move. Unless you are in a fixed position or have access to motorized transport, sheer exhaustion will become as dangerous a threat as the walking dead. Common sense would suggest that a flamethrower’s place on the battlefield is against overwhelming numbers, swarms of undead numbering in the hundreds if not thousands. If such a horde were, heaven forbid, to exist, chances are they would be facing a much larger, well-equipped government force rather than one private citizen and his trusty (and let’s not forget illegal) flamethrower.
Imagination and improvisation are two invaluable assets during clashes with the living dead. By all means, feel free to regard all the materials around you as a cache of potential weapons. But always keep in mind a zombie’s physiology, and what your homemade device is likely to accomplish.
Apart from fire, sulfuric acid is the best way to completely destroy a zombie. Implementing it is another matter. If somehow you have the means to acquire or produce large amounts of sulfuric acid, treat it with the same respect you would an incendiary weapon. Not only is this substance as much a danger to yourself as it is to the undead, the time it takes to dissolve zombie flesh and bone is considerable. Acid should be used as a post-encounter disposal tool rather than a combat weapon.
As there are hundreds of thousands of lethal compounds in this world, it is impossible to discuss them all. Instead, we will review some basic rules that govern the physical and physiological makeup of the undead. Zombies are immune to all types of tranquilizers and irritants such as Mace and tear gas. Any compound designed to halt bodily functions would be equally impotent, as the undead no longer require these functions. Zombies do not suffer from heart attacks, nerve paralysis, suffocation, or any other fatal effects caused by poison.
Wouldn’t it be poetic to destroy beings infected by a virus with another virus? Unfortunately, this is not an option. Viruses attack only living cells. They have no effect on the dead. The same is true for all types of bacteria. Several laboratory attempts have been made to culture and spread necrotizing fasciitis (a flesh-eating bacterial disease) among captured zombies. None have proved successful. Experiments are now under way to grow a new strand of bacterium that feeds only on dead flesh. Most experts are skeptical of its success. Tests are ongoing to determine which of the many microorganisms normally involved in decomposition continue to consume flesh in spite of its infected nature. If these microbes can be isolated, reproduced, and delivered in a manner not harmful to its user, they could be humanity’s first weapon of mass destruction in the battle against the living dead.
