Mathieu Lehanneur & David Edwards (Pumpkin-water bag)

French designer mathieu lehanneur along with harvard professor david edwards have created 'pumpkin', an object that carries water as it conforms to the needs of its user's in both domestic and international aid situations. 

'pumpkin' is part of a three year experiment focused in south africa. an international support group is set to help local inhabitants imagine new ways of transporting water, influenced by the principles of the water vessel, but also by local ingenuity and initiative. the container was produced for commercial sale in locations throughout the developed world in 2010 with profits directed towards the charity. continual experimentation is aimed at improving access to water in some of the harshest environments around the world. 

The vessel for everyday use is composed of two detachable parts that clip together to serve as a shoulder bag that holds up to one and a half liters of water while transporting personal items. when being used for sport, such as hiking, the object detaches from the bag and connects to other tubes that can hold between four and eight liters of water, encircling the user's head or, like a rucksack, slinging around the back. when requiring large quantities, as in hard work or relief conditions, the container can hold up to fifteen liters of water around the shoulders and neck or torso.
