Is it possible to weaponize common tap water in some sort of gun?
Imagine a basic water gun. It doesn't do much damage at all.
But what if we could fire the water out in controlled spurts, at high speeds? Imagine a highly complex water gun. This gun internally controls the amount of water in each shot, and propels said amount of water in a given direction, allowing the water to be used as a projectile.
What are the limitations of this weapon, how much damage could it potentially do, and how would it work?
Note: This weapon must not fire ice. It must fire the LIQUID form of water.
Range wise, I'm looking at preferably bow and arrow range or higher - definitely not close range.
What if we used the water as the "weight" behind the projectile, and a small plate/cone/something were used as a "barrier" in order to stop the water from getting deformed due to air resistance? Would this weapon be plausible?
As long as it's liquid water hitting the target, it passes the "this weapon fires liquid" test.
When designing this weapon, even if we currently don't have the technology to actually make it, as long as the technology is sound and the physics/theory works out, it's okay. (It's okay to go slightly into future tech, but don't think up something you can't explain)
