Can you remove a tank from a paintball gun without it blowing the CO2 everywhere?

If you have never taken off a co2 tank , take it a gun store or a sports store like bass pro shops or cabelas . If you think you can do it by yourself without help , just grab the tank ,on the middle and twist it off . You will need somebody to hold the gun down and who ever will take off the tank will twist the tank like if your opening a jar of pickles.
