'give it up'? that's a bit snarky, lol. I'm doing an engineering analysis from a reasonable perspective, that's all. I'm so honored to be called down by an engineering god such as yourself. Gosh.

Regarding packing enough energy into an ice needle to penetrate skin, I note that the kinetic energy in an ice flechette would have to be very small, as the mass for a water / ice projectile needle would be tiny, tiny compared to even an airgun pellet. Since KE =1/2 m (v squared), the only way to pack decent KE into the object to get any kind of range at all would be to push it very hard, but that would very likely fracture the projectile right away as the shock wave of the push rippled through it from the pusher. So again, I call bullshit on the idea. It's Buck Rogers fantasy.

It would be nice to build an ice chip flinger just to get some experimental feeling for it. I have the feeling ice would break apart at target too easily instead of penetrating. Have to see how shooting ice needles at ballistic gel having a fake skin would work out.

My analysis:

Ice needle calculations

1. Size. Ice needle upper bound: diameter less than an airgun pellet
2. Mass. mass of ice needle estimated less than 1/10 of airgun pellet, which is in range of 1.3 gram hence ice slug / needle in range of 0.13 gram
3. Firing energy. Airguns firing pellets have energy between 7 and 16 joules (from vendor data). Let us estimate ice gun energy in same range, as much higher force would probably fracture the needle.
4. Velocity: so assuming gun force KE in same range as airgun, and with ice mass of 1/10 of a pellet, energy 7 to 16 joules gives ice pellet around 1/10 airgun energy and hence velocity of ice much lower. Based on v= square root of KE/(1/2m) = 2KE/m but since m is 1/10 of airgun pellet, v is 1/10 of airgun pellet
5. Skin penetration:

https://pubmed.ncbi.nlm.nih.gov/7175470/

Minimal velocities necessary for perforation of skin by air gun pellets and bullets.

Extrapolating from data for the lightest airgun pellet .177 which needs 331 FPS to penetrate, the ice gun would have to be fired at more than 500 FPS. Even if ice needle is sharper hence more penetrating, given the KE numbers above, I will say the ice gun can't fire an ice needle with enough force to penetrate skin at any practically useful range. Maybe right up close, but then the scope on the demo gun is BS. Steel needle, sure, but ice, no.

On the other hand, a CO2 based gun might produce more than 7 to 16 joules firing force but velocity is still limited by the lower mass of ice projectile.

Conclusion: the idea of the ice gun seems likely just silly propaganda.
