    hey guys, i just bought a secret strike today. and i thought i'd tell you about the easiest mod i have ever done. This modification doesnt do much to the range but it does alot to the power produced by the secret strike.

    basically there is a slit at the bottom of the secret strikes barrel, all you have to do is cover it with tape
    (I covered it on the inside and the outside)

    The only Bad thing i have discovered about this mod is that smoke or some sort of vapour comes out of the barrel after firing (i'm not sure if this is a bad thing since it looks really cool)

    The vapour your're worried about is simply water. All normal air has a percentage water. When things expand they cool. The air expands out of the tank and cools, this causes the water to condense into tiny droplets.

    umm, Biggles is right here. The air being released from the tank cools down and forms the mist from the moisture in the air. You do get some condensation inside of a pressure vessel depending on the humidity.

When you pump more air in there, the gas laws, for all those who do chemistry or physics, PV=nRT, P1V1=P2V2, where you use the first rule to find the number of moles of oxygen (air). the increase in molecules in the same amount of volume will result in an increase in pressure.

    If you know anything about the water cycle, you'd know that when there is alot of water vapour in the air at the same place, it form water droplets know as clouds..... Same thing happens inside the air tank because you're putting more air (water vapour) into the tank.

    So you know have effectivelly miniscule water droplets inside you tank.

    When you pull the trigger, and opens the valve, there is 2 air pressure systems. One high and one low. they will try to equalise. Normally the low pressure system would slowly seep into the high pressure system and it would equalise over time.

    But because there is no where for the high pressure to got, it equalises violently with the water droplets in the pressurised air.

    You then see the mist spurt out from the gun.

    Now that is 2 years of physics and chemistry and graduating 2nd in the grade for chemistry.

    My dad just just read your statement and declared that you were wrong. When a gas expands it cools, look at an aerosol can. It's also how a fridge works.

    You're dad says he's wrong. Where's his proof. Give us some calculations and shit. Just because you state it doesn't mean it's right. You haven't backed up any of your statements. "My dad declared that you're wrong" isn't backing up anything and doesn't mean shit. I don't give a shit if you're dad is a 20 year engineer. If you're dad personally types up an example of why phounguyen is wrong then . Giving examples of 'how a fridge' works or an aerosol can doesn't mean anything because "how" does gas expansion = cooler temperatures?

    After reading phounguyen's scientific analogy I would be more convinced that he is right, not because I'm his friend (it's partly, but that's the case for most things). A simple example of a fridge, it also uses "different pressure systems", but I dont' really know, I just remember that very vaguely in physics. I know at least that much. Let your dad blow my mind away.

    For something to expand it needs to become a gas, therefore it needs to be heated. Once at a constant temperature (i.e. Room temp.) it then condenses on anything cooler than itself. The air chamber is cooler than room temp. Therefore the water particles condense on the inside of chamber. When the air is released, it spurts the water particles out as a " mist ". Cooling something does not make it expand. Try cooling a glass of water and see if it expands. If you release the air from the gun, if it really did expand, you should have an infinate supply of air flowing from the air chamber.

    Cooling does not expand things, although freezing generally does.

    I disagree with your first statement. Two examples of why
    1. Take WATER --> ICE, you require freezing
    2. Rubber, when heated it expands but not due to a gas

    Err... one of the only (or the only) thing that expands when it cools or 'freezes' is water. If you cool down metal... it will shrink. but it won't shrink significantly enough to be spotted by the human eye. Concrete is a good example.

    When you compress air it heats up, so when the pressure is released it becomes cool. (this make sense to me as when filling air tanks they are filled in water).

    So if i am right, then when you quickly fire the compressed air out, this would cause a small water vapour trail.

    You get this heating effect when you fill your bicycle tyre with air and when it goes pop you may sometimes see the water vapour in the air.

    1. Take WATER --> ICE, you require freezing
    2. Rubber, when heated it expands but not due to a gas
    The reason water expands when freezing it is because it traps the air inside it as bubbles. The only reason that the rubber " expands" is because you're turning a solid into a liquid. When you make something hotter it expands. The state of matter goes like this:

    Solid -> Liquid -> Gas -> Plasma (Although some people claim that Plasma isn't a state of matter)

    To "Advance" forward in these states of matter, the atoms must be charged with heat energy, which makes the atoms move about more, creating a bigger size of the object. To reverse backward in these states, the atoms have to lose their heat energy, which "calms them down". Some elements (e.g. Carbon) skips some of these steps, for example, Carbon cannot be turned into a liquid, so when heated:

    Solid -> Liquid-> Gas

    All of this is true and there is most likely nothing to prove it wrong.

    Cooling = Compression
    Compression = Cooling

    When you compress air you are jamming atoms together, meaning they can't move and create heat, therefore compressing air does not make it hot.

    @servulus

    I believe the reason air tanks are filled in water is to show any leaks.

    When you heat something, the atoms become excited and move around a lot, so everything expands out to make room for this movement, when you cool it, the atoms become lazy and stop moving around as much and are drawn closer together making things shrink.

    The only reason why water expands when it freezes is because a H2O molecule is not perfect, there are tiny little positive and negative charges within it, to explain:

    ....O
    ..../.\
    ..H..H

    [Ignore the .'s, I had to use them for spaces]

    There we have a water molecule, on top of the Oxygen atom there is a tiny negative charge, not much, but it is there, and on the end of both Hydrogen atoms is a tiny positive charge, when water starts to freeze, the negative and positive charges start to join up, making a lattice work of water molecules which is bigger than what it would be if all the molecules are just jammed together, this lattice work also allows frozen water to trap other molecules within itself, hence why there are air bubbles in ice.

    In principle, when you compress things they cool, this is how an air conditioner works, they have gases and a compressor, when the compressor is active, it is compressing all the gases in the pipe work of itself, rapidly cooling it, this cool gas is pumped around the pipe works though big heat sinks when air is pushed through the heat sinks by a fan, cooling the air before it is pushed back out into the room, thus cooling the room

    ok lets get this right. when u compress anything it heats up and when u decompress it and it expands it will cool down. thats why u have an intercooler on a turbocharged car to cool the compressed air down. you cant compress a liquid. and water vapour builds up in air tanks because of the water in the air condensing in the tank.

    ir u have an air compressor a good example is turn it on and let it get to pressure, the tank will be slightly warmer, now pull the water release valve and u will notice water coming out and if u have a high enough volume it will acctually turn to ice!

    It's not cooling because the gun doesn't get cold enough. Take the insides from the inside then fire it you will not notice any temperature change.

    Water can not turn to ice unless it is cooled, compression will also do this because everything is being squashed together, but that squashing also cools because the atoms dont have enough space to move around so they dont move around as much, there is no other way for water vapour to turning into the tiny water droplets

    Having just talked with a scientist friend of a friend of mine, compression heat things up because the atoms are trying to move around in a reduced space, thus giving off heat, however, when this compression is suddenly released, there is a rapid cooling effect because they exert all of their energy expanding out when released, thus cooling, which is how you get the water vapour
