There are many things that can effect the preformance of a BB. Just like wind, elevation, temperature (effects GBB's more than BB's) etc effects a real bullet, it would have the same effect, usually more due to a BB's lighter weight, as a real bullet.

I would think that it would fall shorter than on a less humid day. Then again, I could be, and probably am, wrong.

Sounds plausible to me.

Higher humidity means there is more moisture in the air (more or less).

One would think that would decrease fps, as the bb's must force it's way through.

HMMM

I would think the effects would be negligable, but who knows*.

idk about moisture but I know that lower temps can help a bb travel further because the air is denser meaning more air passing over the bb, and if you add backspin, the air on top is moving faster meaning less pressure and more lift.

Umm, BB's aren't wings.

The greater ammount of matter that the bb encounters on it's flightpath to Sparties goggle lens, the slower it will go.  Doesn't matter if that's air, water, Screwlooses "brown gas", etc.

Now, I'm not certain here, so I refuse to get too heated.  But this stuff makes sense to me.

Any pilots that disagree?

I figure that if I can shoot someone at just the right moment, with the Earth spinning in the correct direction, around the Sun in the correct direction, the Solar system moving around the center of the galaxy in the correct direction all at once, I may be able to propel my BBs to relativistic speeds!

Its all moot.  Worry more about aiming and such. [:P]

Actually i did a bit of research and i'm not entirely sure but, actually humidity should make the bb travel a bit faster, well unless it's 100%. Because the moisture replaces the air and therefore the stuff we end up breathing is thinner. It just feels thicker becuase it tends to condence on anything warmer than it's surroundings... for example the bb, but then again if you fired it from a GBB using green gas it would be colder becuase of the liquid that is released from the mag, which then evaporates creates tons of pressure and also becomes very cold, so yeah theoretically the bb should travel faster. At a neglible amount though so it really doesn't make that big of a difference. I was just thinking about it.

The humidity, even as a vapor is still denser than the Nitrogen that makes up the atomsphere (for the most part). So whatever aerofoil effects the spinning bb's have is probably about the same as in less humidified air, but there is more friction to begin with, so the bb's should not go as far as they would in a less dense atmosphere.

I dunno bro, soounds like you were just speculating like the rest of us.  Sure, you throw out some interesting points in your post, but keep in mind the differences in physics for a smaller object (BB) as compared to conventional changes in atmosphereic conditions.  

Colder BB from coming in contact with green gas?  Not likely.  And according to your theory, the water would condense on the BB, attaching itself in the absense of water vapor.  Now HOW would a bb laden with water droplets travel faster than a dry BB?  

Let's save our thoughts for the next game, when we do not have the luxury of looking up our answers on google.  Cool?

AZSarge,

When it comes to aircraft, the cooler air does make for better performance, purely because the air is more dense, and the wings have more to "grab." Hot days reduce performance for the same reasons. My dad used to fly, and he seems to think that humid air degrades performance.

BB's do actually create lift when they have some backspin on them. The backwards rotation of the BB causes the air around the BB to change in pressure, creating a low pressure area above and a high pressure area below the BB. That's why hop-up works.

So is someone going to take the initiative and try to prove their theories, or are we just gonna chat it to death?

Science has a funny way of making everyone look stupid.
