  Combustion, sure, but not an explosion.

  I hate to do this to you, but that’s kind how explosions work (i.e. combustion).

    More specifically, that’s how cars with a combustion engine work: lots of tiny explosions.

      No, they’re a combustion event. An actual explosion (detonation, pre ignition) is really bad news for an engine.

      Firearms use a self oxidising propellant, so it would be quite easy to say that just doesn’t work.

        What, pray tell, do you think is in gunpowder? It’s not magic dust that goes bang. It’s a pre-mixed, pre-compressed mixture of fuel and oxidiser. When used in a gun, whether it’s a muzzle-loader or a cartridge, the confined combustion of the mixture generates thermal energy and expanding gases that impart kinetic energy on a moving component (the piston or a projectile). The only difference is that the combustion event in an ICE is subsonic (deflagration) while the combustion in a gun is supersonic (detonation).

    Don’t be coy, you absolutely love doing this.

    Nope, there’s a fundamental difference between a fuel/air mixture burning and something like gunpowder, which is a self oxidising propellant. Most explosives are in the latter category.

  Explosions are combustion.

  And really we’re just talking about oxidation. If oxidation works (which it must, because the characters are breathing) then chemically-propelled projectiles must also work.

    Look, we’re talking about a world where people fly around on broomsticks like we ride bicycles.

    Of course you can just declare that firearms don’t work.

      I mean… not if your fantasy world has any internal consistency… and if it doesn’t then it might as well be Cloud Cuckoo Land.
