Spider-Man's most important pieces of equipment are his webshooters. Worn on both wrists, they allow him to shoot lines of high-pressure web fluid. These web-lines can be used to swing from building to building - or can be modulated to manufacture web-shields, web-balls, web-cocoons, or even web-gliders.


If you don't care to read more about the Web-Shooter, take a look at the Web Designer.

1. Web-Shooter: The composition of the fluid itself is unknown, but has many of the same properties as Nylon. It is contained in web cartridges under high-pressure (300 psi), which can be inserted into the shooters. The shear-thinning webbing chemical is in an almost-solid state, until shearing force is applied to it using a tiny turbine pump vane. It is then turned into a liquid, driven through the turbine and out the spineret.

This "cold-draws" the webbing, giving it extraordinary strength. The tensile strength of the webbing is estimated at 120 pounds per square millimeter. Upon contact with the air, the webbing molecules knit themselves into long, flexible and adhesive fibers.

The longer Spider-Man's webbing is exposed to the air, the less adhesive it becomes, although it stays very sticky. After two hours, the chemical bonds disslove, and turns to powder.


2. Spineret: The wristcuffs have palm triggers, made of spring steel, which require 65 pounds of pressure to acitvate. A small spineret nozzle placed at the base of the wrist can adjust the diameter of the web from very thin strands to wide web sprays. They are made of high-tensile steel, and have a single hinge which allows them to be easily removed. The cuffs have several places where web cartridges can be inserted.

Webs are an integral part of Spider-Man's fighting strategy, as well as serving as his mode of transportation, and a convenient method of detaining subdued criminals. Spider-Man can use his webbing for a wide variety of different things. He can make various objects including shields, concentrated webbing balls which he uses as projectiles, nets for catching falling people or debris, and anything else he can think of.

This diagram gives a more detailed look at the complex spineret mechanism.
