Whether you are interested in engineering, chemistry, or just like the concept, the prospect of web shooters has enthralled audiences for 50 years and counting. Taking that concept a bit farther, we here are attempting to make our own web shooters. My name is wadaltmon and I have been working on this project for 6 years and now have a working shooter and am now currently working on the formula. With perseverance and hard work we can accomplish our ultimate goal of building the web shooter!
Yay, a new start to the thread, with Part 3. As WW used to do, might as well put in an introduction.
Anyway, @Hii... no problem. Ask as many questions as you want, I'm here to answer them. Also, about the basketball pump nozzle... sorry, I got off topic on that one. Yeah, you can use it, but most have holes on the side of the needle, so you should either cover it or trim the needle down so there is no longer a hole in the side. And yeah, White_widow used a soda bottle for his first tank, so I assume you can use one. Depending on the formula, 150PSI could shoot a range of distances. I think I had my tank around that 100PSI, and when I shot water, it went around 7 feet; there is a video of it on my Youtube channel. To heat the spinneret, you should take nickel-chromium wire, wrap it around the spinneret, and attach it to a 9V battery and possibly a switch on the trigger, so it only heats when you are shooting and you're not wasting battery. You can make the spinneret out of anything you want really, as long as it doesn't dissolve from your formula or breaks from the high pressure. The metal nozzle thing should work. About the pressurization thing, have you ever seen the things called SodaStream in stores? It's a thing that allows you to make your own soda by putting in a soda base and carbonating it. They sell big CO2 canisters for them for the carbonation of the soda, and you could connect one or two CO2 canisters to your tank, but it might be high pressure and cause the tank to burst. I guess you could just put a little valve on it, that would open kind of like a faucet, to regulate the CO2.
EDIT:
Here is the SodaStream thing, and
here is a picture of the CO2 thing.
Here is a picture of the valve on the CO2 canister and
here and
here are little regulator things for it (I would suggest zooming out on that first picture of the regulator).
