I was wondering if a freeze ray could be possible. Can anyone help me out with this?

Well mabye not a ray but some CO2 is great.
The CO02 in the fire exstinguisher one is cool.

Could CO2 be used in the form of a weapon to capture or kill someone/something?

i suppose you could use liquid nitrogen but you mean a beam hrm is this possible with liquid nitrogen?

I would imagine that some sort of device that can emit a burst of liquid nitrogen would, in itself, be a type of "ice gun."

Liquid nitrogen evaporates REALLY fast though, so either you'd have to have a high pressure and a high volume, or you'd just have to be very close to the target.

I'm curious wether or not a weapon could be made that has the same result that freezing weapons in the movies are possible. ie A guy gets hit and his body is frozen solid at which point he could be, well, shattered.

cmdkid, you must be the genius I heard so much about. Nice to meet you.

Got me thinking - what about a wave or particle which does the opposite to what microwave ovens do. Where as the microwaves "excite" the water molecules, this proposed beam would absorb the internal energy of the water molecules - thus lowering the average Kinetic energy of the water molecules and ultimatly temperature.

I believe some laboratories use laser cooling to grab those extra few degrees Kelvin near absolute zero to generate Bose-Einstein condensate. This is very small scale though.

Actually, I think lasers have been used in experiments to 'cool' gases and the like. I have no idea how this is supposed to work tho, it seems entirely counter-intuitive to me. I doubt it'd work in a way that coudl be used against people anyways.

I think that it works by using an array of different lasers, I guess that they 'hold' the particles in place or something.
