A Canteen That Expands to Carry More Water

A Canteen That Expands to Carry More Water

French designer Mathieu Lehanneur has dreamed up infographic-enhanced urns and plant-powered air filters.

Lehanneur sees his Pumpkin being suitable for rugged hikers or international aid workers. Once detached from the shoulder-bag portion (which, to be honest, seems more First World clever than Third World practical), the water tubes can be chained together to form larger rings which can carry more water while slung around the shoulder or waist. In these situations, the Pumpkin can accommodate between four and eight liters of water.

It was sold throughout the developing world in 2010, with profits redirected to charity, and it’s currently on display at Le Laboratoire in Paris. Can your Army surplus canteen boast that kind of cred?
