marvel - How does Spider-Man control his webbing?


In the cartoons, I've seen Spider-Man shoot a variety of webs from his web-shooters. the ones I can name now are:



  • Globs of sticky webbing

  • Lines of swinging webbing

  • Sticky lines of webbing



If these all come from the same device, how is he able to choose which type of webbing is shot?


(I'm as interested in the comics as the cartoons FWIW.)



Answer



Marvel's official website has this diagram of Spider-Man's web shooters:


enter image description here


The Wikipedia entry on Spider-Man's webbing states simply that Spider-Man "can do many things with his webs" and lists many different types of webbing (the ones you listed included). All of these different types of webbing come from the same shooters; they just occur when the wrist devices are used differently.


To paraphrase the Marvel Wiki (emphasis mine):



The wristlets had sharp steel nipples which pierced the bronze caps when the cartridges were tightly wedged into their positions. The hand-wound solenoid needle valve was actuated by a palm switch that was protected by a band of spring steel which required a 65 pound pressure to trigger... The effect of the very small turbine pump vanes was to compress (shear) the web fluid and then force it, under pressure, through the spinneret holes which cold-drew it (stretches it: the process wherein nylon gains a four-fold increase in tensile strength), then extrudes it through the air where it solidified. As the web fluid exited the spinneret holes, it was attracted to itself electrostatically and thus could form complex shapes. The spinneret holes had three sets of adjustable, staggered openings around the turbine which permitted a single web line, a more complex, spun web line, and a thick stream... The 300 p.s.i. pressure in each cartridge was sufficient to force a stream of the complex web pattern an estimated 60 feet (goes significantly further if shot in a ballistic parabolic arc).

harry potter - Did Dolores Umbridge Have Any Association with Voldemort (or Death Eaters) before His Return?

I noticed that Dolores Umbridge was born during the first Wizarding War, so it's very likely she wasn't a Death Eater then (but she is pretty evil -- who knows?). After that Voldemort was not around in a way that could affect many people, and most wouldn't know he was planning to rise again. During that time, and up through Voldemort's return (in Goblet of Fire ), did Umbridge have any connection with the Death Eaters or with Voldemort? Was she doing what she did on her own, or was it because of an association with Voldemort or his allies? Answer Dolores Umbridge was definitely not a good person. However, as Sirius points out, "the world isn't split into good people and Death Eaters". Remember that he also says that he doesn't believe Umbridge to be a Death Eater, but that she's evil enough (or something like that). I think there are two strong reasons to believe that: Umbridge was proud to do everything according to the law, except when she trie...

What is the etymology of Doctor Who?

I recently decided to watch Doctor Who, and started viewing the 2005 version. I have the first two episodes from the first season, and I can't help but wonder what is the etymology of the name "Doctor Who"? And why does the protagonist call himself "the Doctor" (or is it "the doctor")? Answer In the very first episode of Doctor Who (way back in 1963), the Doctor has a granddaughter going by the name "Susan Foreman", and the junkyard where the TARDIS is has the sign "I.M. Foreman". Barbara, who becomes one of the Doctor's companions, calls him "Doctor Foreman" (probably assuming that is his name given his relationship to Susan), and Ian (another early companion) does the same in the second episode, to which the Doctor says: Eh? Doctor who? What's he talking about? "Foreman" is most likely selected as a convenient surname for Susan to use because it happened to be on display near where the TARDIS landed....

story identification - Animation: floating island, flying pests

At least 20 years ago I watched a short animated film which stuck in my mind. The whole thing was wordless, possibly European, and I'm pretty sure I didn't imagine it... It featured a flying island which was inhabited by some creatures who (in my memory) reminded me of the Moomins. The island was frequently bothered by large winged animals who swooped around, although I don't think they did any actual damage. At the end one of the moomin creatures suddenly gets a weird feeling, feels forced to climb to the top of the island and then plunges down a shaft right through the centre - only to emerge at the bottom as one of the flyers. Answer Skywhales from 1983. The story begins with a man warning the tribe of approaching skywhales. The drummers then warn everybody of the hunt as everyone get prepared to set "sail". Except one man is found in his home sleeping as the noise wake him up. He then gets ready and is about to take his weapon as he hesitates then decides ...
