Miller Lite Vortex Bottle

Miller Brewing Company have a new idea to sell more beer. It's called the Vortex Bottle. The bottle has angled grooves inside the neck in order to deliver the beer quicker and more smoothly to it's destination. Science (and nature) has proven that air or liquid will move quicker and easier through a tube if it is rotating, hence the rifling on the inside of the bottle.
