Well, not easily, at least from my POV, I'm taking a heated needle and puncturing holes in a metal tack, then welding it to a long thin piece of metal that attaches to a motor in the back of the shooter.how do you actually make a spinneret?
On the other hand, I was at a Tradesday in Weatherford today, and I bought one of those old toy web shooters I used to play with back when the Tobey McGuire movie came out. Surprisingly, that little silly string toy gave me some ideas.
Why not utilize this simple idea in a shooter? If I remember right WW was making pressurized cartridges, maybe I'll try and make something to that effect, a plug-able cartridge into a main nozzle. At Walmart they sell extremely small flasks. And whatever the formula is for silly string, as ridiculous as it may sound, couldn't some polymer adjustments and hardening agents make that suitable formula?
