It’s Carb as in Carbonator in a car. Which mixes gas with air.
This carb mixes smoke with air (usually in a pipe)

When bongs have them we usually call them shot guns. As bongs usually have a pull out bowl.
Cuz they shoot you in the chest
harris7 Reviewed by harris7 on . How to smoke from a bong? ...Confused I know i might sound like a dumbass but how do you smoke from a bong?! Ive been dying to find out. I get the main princaples like you light it from the bowl but how does the smoke travel from the bowl to the chamber with water? Do you inhale and the smoke will enter the chamber or what because the other part of the bowl piece is submerged under water so inhaling wouldnt do anything. Im just confused...any help would really be appreciated since i have yet to smoke from a water bong. And Rating: 5
