Ok so a bong has a neck (the skinny part) and the chamber (usually round) where the water is kept. close to the top of the chamber is a hole called the carb and near it should be the bowl which goes into the chamber via a stem. Some bongs can have either a carb or a detachable bowl.
ok so u fill it up w/ water at least and inch below where the stem meets the chamber. now u put our mouth on the bong and ur finger over the carb and light the bowl and suck in and if u got a good bong, the smoke will fill it up until it condenses into a milky white smoke. now u let ur finger off the carb (or pull out the bowl if ther's no carb) and inhale the smoke.
phew.....that was alot of writing.:jointsmile:
