Beers filling up through the bottom

You are probably wondering how the  hell this thing works, well... There is a magnet inside the cup which seals against a metal ring, when placed on the dispenser the magnet is raised to allow the beer to enter the cup and when the cup is lifted the magnet seals the cup again stopping the beer from draining out the bottom. Tilting your glass or cup whilst pouring your favourite ale is so outplayed. Can't wait till this hits our shores.
