Beer-Dispensing System Will End Ballpark Lines | Playbook
Its all based on magnets how do they work? that open up a valve on the underside of the cup when its placed on the Bottoms Up beer-dispensing unit. Once the beer (flowing in at a tremendously faster pace than scientists or drunk ballpark patrons ever assumed possible) fills the cup enough, the valve closes and all you have to pop the cup off the stand and off you go, legal drinker.
