Avoiding turbulence is key to pouring out a bottle quickly and poor airflow causes turbulence. If we can find a better method of supplying air we can pour the spent soda out faster. Spencer's Gifts has solved this problem as well as the age old college problem of not getting drunk fast enough with a special beer bottle attachment which has a straw to relieve the back pressure; however, I found a better method with no additional equipment required: The Tornado Technique™. (Note: when pouring into your mouth, it's a lot less messy to use the attachment.)
The Tornado Technique™ is simple, just twirl the bottle as you pour it out so that the liquid inside starts spinning. As gravity pulls the liquid out it adds energy to the spin which transforms it into a self sustaining whirlpool. As the whirlpool is draining into the sink the replacement air will come up through the center. No more waiting! Alternately, if your goal is to pour the bottle out as slowly as possible in order to just watch the tornado, there's a bottle attachment for that too.
