Playing paintball is fun, although it's painful and leaves you with a bunch of bruises, there's also a lot of physics seen in the activity. If you've ever gone, you probably was put into an area with a bunch of other people, hopefully armored and protected with masks so you don't get accidentally shot in the face because the paint balls are moving at fast velocities once shot from the paintball gun with the help of a CO2 tank. The way the paintball gun works is, the tank filled with CO2 will apply pressure on the paintball, once the triggers pulled, it releases the paintball sending it towards the opponent it was aimed towards. Being a first timer, my aim was especially a little off, and that made me an easy target. Luckily I'm great a hiding, so all the dirty work was done by everyone else most of the time. But going back to the paint balls, each time they're fired, it's not going to have the same trajectory at which they fire, this either being the angle you're holding the paintball gun, or just because each paintball isn't exactly the same. It's not a perfect sphere, and there will be occasional imperfections with them that can cause a change in distance and the velocity. And because of gravity, all of the paintball's which were able to survive colliding into any person or surface and popping would end up on the ground. Paintball's a great activity to go out and do with family and friends, but beware of those small paintball's because even though they're just little balls of paint, they can cause a great amount of damage.
