These two videos show the amazing “Bottom’s Up Draft Beer Dispensing System," which “pours” a draft beer nine times faster than traditional methods and dramatically reduces spillage. It's made by a Washington start-up company named GrinOn Industries, whose president Josh Singer saw it a way to end the dreaded stadium beer line, according to Yahoo Sports.
"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 (see video above). The cup can then be lifted off and the beer consumed as normal. A single stand has been able to deliver 56 draft beers in one minute, an unofficial world record (see video below)."
