Negative-Space Packaging

ColaLife asks an intriguing question: "Coca-Cola seems to get everywhere in developing countries, yet essential medicines don't. Why?"  Coke is highly profitable, so it's developed a huge distribution network to every corner of the planet - a network that can be piggybacked by a clever design to help bring crucial anti-diarrhea medicine to those who need it. ColaLife's Kit Yamoyo is designed to fit in the "negative space" of a Coca-Cola crate, nestling between the bottles without adding any volume to the overall package. This way, it can utilize an existing distribution system to help people at virtually no cost. It's almost enough to make selling sugarwater seem noble!
