It actually will depend on the paintball gun you have. Typical markers do not need a cartridge, but a hopper (the thing on the top of the gun to feed in paintballs). Markers like the Tippmann TPX and the Kingmann Chaser and Eraser definitely need cartridge to hold the paintballs sense they are pistols.
No. The majority of paintball markers can use any brand of .68 caliber paintballs. Some low end guns cant use high end paint without breaking and using cheap paint in a high end gun defeats the purpose. But any .68 caliber marker can shoot any .68 paint. The exceptions are .43, 50 and first strike paintballs which can only be fired by markers designed to shoot them.
No, some paintball guns share common parts, but they are mostly different. All air/CO2 tanks and hoppers will fit all paintball guns, and regulators and macroline adaptors have standard threads which will fit if you have a regulator port. All barrels and some feednecks have different threading which means they can only go with certain guns. Any attachments with mounts must go with the correct size rail. ASA's have either straight or staggered holes.
yes, you will not have any issues
yes, to any gun made in the last 15 years
There is no reason to put a paintball gun in a refrigerator, or any appliance for that mater.
The paintball gun does not use any parts that have not been make in other industries before.
A Co2 gun can go up to 300 fps. Sling shoots only get a paintball up to 240.
The purpose of a paintball gun is to fire paintball pellets, to mark opponents in the game of paintball.
All paint ball guns with a regular barrel will shoot around 300 feet. there also is no specific "ak 47" paintball gun

A paintball marker is a paintball gun. It is just called a marker instead of a gun.
you need Co2 to fire any paintball gun, it is what physically moves the ball out of the barrel.
