From ColaLife website: "The AidPod is at the heart of the ColaLife model. It is a wedge-shaped container that fits between the necks of the bottles in a crate of Coca-Cola. The original concept for the AidPod, was to make use of that unused space to get simple medicines, such as oral rehydration salts, and other social products like micro-nutrients to the places that commodities like Coca-Cola get to i.e. most places." The packaging is dimensioned to contain the right amount of water to take the medicines and it is made with recycled PET.
