Having Spider-Man web shooters attached to both wrists would be an impossibly awesome day. Of course, with the reflexes and upper-body strength of the average comic book reader, wed all be dead by the early afternoon, but hey, what a morning! Peter Parker, chemistry genius that he is, created the special web fluid whilst he was still in High School and he has tinkered with the formula in various ways ever since. He keeps it in highly pressurized cartridges that are held in metal wrist holders and can be sprayed out via a quick double tap on the palm button. Once pressed, the device shoots out a line of the sticky fluid that will stick to whatever he aims it at. It is strong enough to carry a great deal of weight, which means that it can be shot from one building to another, as the user swings through the concrete jungle like some sort of urban Tarzan. Sounds like a great way to avoid traffic to me! The devices were designed by comics icon Steve Ditko for Spideys first appearance in Amazing Fantasy 15 (1962) and have never gone away for long, one notable exception being the black costume - AKA Venom - which produced the webbing internally.
