Web-Shooters are Spider-Man's primary tool for crime fighting. As the name implies, it can shoot webs to restrain criminals and be used as a means of travel.
The Web Fluid, the substance that these webs are made from, is made by Peter himself. The webs are able to increase their thickness to half an inch, they are fireproof, they are capable of stretching to a limited degree, and they dissolve after one hour.
The Web-Shooters themselves are a pair of wrist-mounted mechanical devices that can shoot thin strands of "web fluid" at high pressure. The triggers are located in the palm, and require a sixty-five pound pressure to activate them. Each web trigger is situated high on Spider-Man's palm to avoid most unwanted firings. An additional safety measure, to prevent misfires when Spider-Man makes a fist or carries something, the trigger has to receive a double-tap from the middle and third fingers.
Trivia[]
It occurred to Stan Lee that Spider-Man could not naturally shoot webs, who found the idea of web coming out of a guy's hand unpleasant. By giving him mechanical web-shooters that he creates would show how brilliant he was. According to Stan Lee the mechanical web-shooters inspired story ideas for when Spider-Man found himself out of webbing when he needed it the most.
In the Sam RaimiSpider-Man trilogy, created before Disney acquired Marvel in 2009, Spider-Man has organic webs rather than mechanical web-shooters.
However, in early development of the 2002 Spider-Man film, Spider-Man was almost given mechanical web-shooters. Before the idea was scrapped and replaced with organic web-shooters, James Carson designed pieces of concept for the mechanical web-shooters. A design was approved and put into development. The early trailers showed Peter Parker (Tobey Maguire) wearing web-shooters, and they also made a brief appearance in the theatrical release. The unused web-shooter props for the Sam Raimi trilogy were sold off on Ebay.[1]
