So many times a great, life changing solution can be made that is high design and decidedly low technology. This is the case with the Hippo Roller, which allows for easier transportation of life sustaining water to villages and dwellings in remote areas. Each roller can carry up to 90 liters (24 gallons) of water, and can last up to 6 years. Already over 46,000 rolled have been distributed in over 20 countries.
