Oct 4, 2016 at 10:35 comment added Nick Volynkin if you left it in one place for long enough - this "long enough" is as close to "instantly" as the weapon's temperature is close to absolute zero. The ice on the blade would actually be frozen air, not just the water vapour.

Oct 3, 2016 at 23:17 comment added Paŭlo Ebermann I don't think you can split oxygen from nitrogen just by stirring them with a cold stick – their boiling point is quite near to each other, so you would get a liquid mix of both. (I also don't really get how your liquid oxygen would give you explosives, that might need a bit of elaboration.)
