As long as you can fit a can/bottle/pint of beer into the funnel without overflow, you should be good. If it only fits one at a time, and you want 2 or 3, just have a buddy pour more in while you're drinking. :p
Beer bongs are fun, but they're the funnest when you find a tough talking drinker who's never used one, tries it, and ends up wasting half the beer because they can't chig it down. :p It sprays all over the place and gets all over you. Very embarrasing in front of girls.
