The video you see above is of BottomsUp Beer, a dispenser that actually fills cups from the bottom rather than the top. It's made by a company called Grin On Industries and it claims it can fill a beer cup nine times faster than traditional taps. This removes the foam that frustrates any beer drinker.
↵Now, it's coming to the Verizon Center. Ted Leonsis just announced that he has purchased one and it will be ready for use for tonight's game against the Wizards. (UPDATE: it was used at last night's Capitals-Sharks game). How does it work? Here's a quick primer by Wired.
↵↵↵↵It's all based on magnets - how do they work? - that open up a valve on the underside of the cup when it's 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.

Once again, Leonsis and his team is on the cutting edge of new technology. Now, you no longer have to wait in long lines to get good beer. Whether you're cheering on Leonsis' strong team (the Capitals) or trying to drown your sorrows about his struggling team (the Wizards), now you can do it more efficiently.
