Why must we be forced to bong beer from bottles or funnels? Why not let the beer drinker decide? I want a world where people don't have to be ashamed for showing up to parties with canned beer anymore. I want a world where bottles and cans can work together in drinking harmony. Well my friends, you now have a choice! Let your canned beer join the party! It can empty any 12 ounce can in less than 3 seconds. It is very easy to use, simply open the can , and snap it on. It is a gravity powered beverage dispensing system.
