Beer Bong Funnel

How to make beer in a beer bong no foam?
I made a pipe of very good beer and a funnel and valves. It foams up a bit though more than you want and I wondered if I could poor tube something or do something to stop foam less than it is now.
oh I do not know after pouring the beer into the bong and there is foam right? if you do not find to be unpleasant, rub your finger across the cheek bone or the side of the nose (the outside). If you find it unpleasant to do that, rub the finger with the thumb a few times in his place. Place the tip of your index finger just rub into the beer foam (Not the beer, the foam). Leave the tip of his finger in the foam for at least 5 seconds, then remove it. Watch the foam start to disappear before his eyes. Delete the foam by balancing the pH of the oils found on the surface of the skin. maybe that will help
