You've heard the phrase "open source" before, haven't you? If so, then you know it usually relates to software (where the source code is "open" to everyone to see and make changes to). Well, some folks got together and decided to start a soda company called OpenCola. And guess what, the "source" (or in this case the recipe) is open to the public.
Sadly, the company is now defunct (it was originally meant to be a promotional product for computer trade shows), but the recipes and instructions are available to anyone who wants to try his or her own hand at making soda.
Download the pdf "Source Code" (aka brewing instructions) and see what you come up with.
