But firstly, how do you think I'm going to do it? Well, how could I do it? There are tons of discussions on the internet about ways it could be done, and most of them seem to be taking it a bit too seriously, if I do say so myself. To create web shooters that are exactly like those depicted in the comics is impossible. With today's technology, at least. To my knowledge, there is no liquid that can expand to fill a space hundreds, if not thousands of times greater than that which it filled originally (which is what the web fluid would have to do, for one cartridge to allow him to swing through the city at great length). So that's completely out of the question.
If I was doing it (and oh look, I am!), I would forget the idea of the webs being contained in a cartridge of liquid, and instead have them already in the form of some type of string. Which is what I'm going to do. And I'm also not going to pretend that I can make this device shoot a series of many "webs." This will be more like a wrist mounted grappling hook, which will wind back into the device after I've fired it. I'm not sure exactly what I'll attach to the end, though. Maybe some kind of foldable hook...
But how am I going to fire it? Good question. And again, as with the wall climbing gloves, I'm using a tried and tested method for this. I'm sure many of you know of Nerf guns. They're stylised toy guns which fire foam darts. Most of them are spring powered, but one of them, called a Rayven, is electric. One of my [previously referenced] highly dubious friends owns one of these (well, two, but anyway), and when I went to see him a few days ago, he took it apart to tamper with a certain restrictor, meaning I got to see how it works. Inside it, just behind the start of the nozzle, there are two wheels (horizontal), spun by electric motors. A mechanism pushes the dart at the top of the pack forward, into the gap between the two wheels. These send the dart shooting through the nozzle towards the poor child fleeing from my highly dubious friend.
Anyway. That's basically how I'm going to do it. There will be two wheels spun by motors at the front of the web shooter, and a mechanism will push the contraption on the end of the string through the middle of them, sending it shooting out at a wall or whatever. However, I do not own a Rayven, so I cannot simply take one apart and use the already set up motors from that.
Fortunately, I am reliably informed that R/C car motors are more powerful (most certainly quite a bit more powerful if you think about it). So, about a week ago, I took apart an R/C car I had lying around in the attic (hadn't been used for years and the battery was long gone, so I was hardly going to miss it) and removed both motors. However, only one of the motors actually drives the car forward. The other one just turns the wheels left and right, so that undoubtedly won't be very powerful. However, I might use that for the mechanism to push the contraption forward (depending on how I decide to do that).
Anyway, for the actual spinning wheels, I'm going to use the powerful motor from the R/C car - the one that actually pushes it forward. However, obviously, I need two of them. To my knowledge, there are two other R/C cars in my house. So I'll take one of those apart and use the motor from that.
And that is, essentially, it! As I've said before, this project is the one I'm most confident in. It might not actually allow me to swing from buildings, but I'm certain it will be able to shoot a fairly decent distance.
