Standing up: he uses a urinal or toilet. Sometimes they have urinals in portapottys. He unzips his fly, and lets it rip. When he is done pissin', he'll usually "shake" his ****. This is because the urine travels a long distance through the urethra (the tube that leads to the opening of the ****), and after the bladder is empty, there is still drops of urine in the urethra.
A cartridge consists of a cartridge case with primer, the powder filling, and the bullet (the projectile). When a cartridge is fired, the primer ignites the powder, which burns, driving the bullet out of the barrel. The now empty cartridge case may be automatically ejected from the gun (falls to the ground) or may have to be ejected by hand- depends on the gun.
Yes it does. It's called oxidation. When your chlorine is exposed to the air it will lose it's effectiveness. Try this: Empty some out in another bucket, then empty the rest into a regular plastic garbage bag, put the bag back into the bucket, then add the rest. Remember to twist the top and get as much air out as possible. This will help.
