You simply slide it onto the tip of the whipping cream can and Viola! You press down on the button to let whipping cream come out! This would mainly be used for if you're going to spray a lot of whipped cream in one sitting, to make sure the your hands are as clean as possible by staying away from nozzle. And you would have to reach in as much. I would recommend to use a strong filament to prevent it from bending and be able to let out a lot of whipped cream. Have Fun!!
