Can be a profesional whip cream device, which can be used to suck straight from canister (warning: this method can be dangerous as the gas is cold and may damage your lungs, also comes out at a very high pressure and can inflate your lungs) or can use to inflate balloon which user can inhale from.
Home made nanganators are also very common as professional whip cream makers can be costly. Home made nanganators can be fashioned out of plumbing pipes, or also even one simple piece of hose.
In each case a nail is driven through the nangantor and through the top of the foil on nang (this can be dangerous as the high pressure may blow the nail out of the top at high speed) the gas is then captured in a balloon and inhaled from.
User warning. Always take breathes of oxygen between nitrous breathes. Last breathe of nitrous taken from balloon can be breathed back into and used once or twice more.
Nang lover 2: Yeah man! I'll go grab my nanganator.
