I skimmed through an article in "Shotgun News" magazine about Airsoft and from what I hear, they shoot plastic balls. I know balls arent all that accurate, and I do know you can correct some of that by giving the ball a spin as its shot... but how do you spin it with a spring?

They also have CO2 and some other gas out there that they use for AS though, I''m just wondering how all this works.
