pressurized reservoir/CPS Tube sniper rifle

Here's a nother innovation I just thought of! It's complicated, and I'm not sure its even remotely viable, but I was thinking, the main thing that makes a bullet go is that it has that barrel behind it filling with pressure. The problem with supersoakers is that the barrel (tube, in this case) LACKS pressure. So, what if you mount your trigger/firing mechanism back in the gun and connect it directly to a thin, medium thick, long tube that can expand and contract, like a very thin extended cylindrical CPS. The firing valve would be attached to a one way valve feeding into the barrel tube, and the water would be forced outwards, in theory, gaining velocity with every inch of cps tubing!

What do you guys think? Home Made gurus, I'm looking in your direction.

here's a poorly done diagram to help if I didnt explain it right

Doesn't work that way is my thinking. Any tube between the trigger valve and the nozzle will decrease performance as it will cause the water to experience drag. I don't think an elastic tube will be any different.

In a water gun, everything up to the firing valve is under the pressure that the PC produces. After the firing valve, I'm not so sure, but the pressure can't abruptly drop to zero. You'd probably need calculus to work things out.

In order to boost water gun performance, you rather want to have the nozzle as close to the trigger valve as possible. And in general, the design needs to be based on fluid dynamics.

The PC will always be the source of highest pressure; feeding its pressure into a second tube or PC will decrease it as the pressure will be shared between the two. (the amount decreased depends on the pressure of the second PC and the volume it allows) The highest source of pressure should always go directly to the nozzle, preferably with some laminators.

Even if you could make the gun, the tube would try to absorb most of the force by expanding lengthwise and width wise. It would essentially take all of the "Soak" out of Super Soakers.

good points all, I guess I should have given it more thought. Theres just no way to expand too greatly on the range of a supersoaker except for the pressure chamber. If anything my idea was more similar to the Splashzooka now that I think of it.

Thanks guys!

What would happen if we decided to make a homemade splashzooka, and made it fillable by any standard hose? We could actually provide a simple homemade for the average builder and have a decent backup gun. I'll start working on some plans.

Ya, I was thinking about doing that too. But I have other plans.
