GrinOn has developed a method for dispensing beer from the bottom, allowing the cup to be filled nine times faster. The post includes a video of them pouring fifty-six beers in sixty seconds.
The key is the use of a cup that features a hole at the bottom and small, circular magnet that rests over it. When placed on the system, the magnet is lifted up by the pressure-driven beer. The cup fills up until the weight of the liquid pushes the magnet back down over the hole. The cup can then be lifted off and the beer consumed as normal.
