Paintballing is a very popular sport. A paintball gun, actually called a paintball marker is demonstrated and talked about in this video by Michael Glatzer. The marker in the video is bright and flashy so that it does not look like a regular firearm. Michael will be able to use this in competition. The part on top of the marker is called the hopper. This is were the paintballs go. On the bottom of the rifle is the air source. Michael demonstrates shooting 10 bolts per second. To keep a paintball marker from firing there are three ways. One is to remove the paintballs from the hopper, two is to remove the bolt and three is to remove the 9 volt battery.
