Ledeni metak ( zna li neko nesto o ovome )

Ivan Dimkovic: Osim toga, promrzline takvog tipa ce sigurno biti jako sumnjive policiji, i..

blaza: Zar supljina nastala usled eventualnog dejstva 'ledenog metka' ne bi bila sumnjiva policiji? Ovo nas vraca na pocetak: cemu bi uopste sluzio ledeni metak?
Offtopic : Ledena strela bi verovatno bila moguca.

Ivan Dimkovic: Zar nije onda lakse napraviti ledenu nozekulju, i zabosti je u vrat zrtve :-)

Ili ledenu toljagu - raspalis sa istom, zrtva umre od ozbiljne head-traume, a toljaga se otopi :)

PS - cemu to? :)

The following weapons technologies also do not exist, or are impossible:

* an underwater rifle which can send jets of liquid water with enough force to break bones.
* a snow rifle which compacts snow into ice projectiles similar to bullets
* a desert rifle which can melt sand and mold it into glass projectiles similar to bullets

* The underwater rifle is the most feasible of the three weapons mentioned. However, it cannot be as powerful as Dan Brown claims.

* The snow rifle is not feasible simply because ice is unsuitable as ammunition. Firing an ice bullet would, under most circumstances, melt it, either due to friction or the heat of the propellant. And if the bullet does not melt, it will shatter since ice is brittle. The feasibility of an ice bullet propelled by gunpowder has been disproved by the Discovery Channel program MythBusters.

* The desert rifle is also not feasible, or even advantageous, because the temperature needed to melt sand into glass (in excess of 1500° Celsius) requires a power source that will take up much more space than regular ammunition. There is also the problem of insulating the heat from the molding unit to prevent burns to the soldier or heat stress to the weapon. In addition, very few deserts on the planet are sandy deserts.

* Brown's hypothetical weapons may be an extrapolation of a real military field manual titled TM 31-210 Improvised Munition Handbook the Improvised Munitions Handbook, published by the Department of Defense. However, this book describes improvisation methods such as field-made gunpowder, makeshift projectiles, etc. No allusion is made to rifles that are capable of manufacturing ammunition of the kind mentioned in the novel.

Evo jednog dela sa Wikipedije o ovoj knjizi gde se negira postojanje ovakvih tehnologija. Napomenuo bih da članak ne navodi izvore pa možda i nije objektivan:
