Kind of neat!

"The Hippo Roller is a simple rolling barrel device that allows the millions whose livelihoods depend on the daily fetching of water to more easily access and transport their daily water supply, and reduce the risk of long-term bodily injuries. The roller holds 3-4 days worth of water for a family of 7, about 5 times the amount of water that can be moved using traditional methods, which frees up time for more productive economic and educational activities. It’s an amazing product and an amazing story of good design enabling communities."
