32 choices! – “Ipifini’s Programmable Liquid Container technology employs buttons on the container’s surface that release additives (flavors, colorants, fragrances) into the liquid. Additive buttons allow for the consumer to choose variations of the liquid in the container at the point of consumption. For example, a programmable cola bottle with buttons for lemon, lime, vanilla, and cherry flavors as well as a caffeine button allows for thirty-two potential choices of soda.” [via] – Link.
