A Coffee/Tea Tumbler that Gives One Person Clean Drinking Water for a Year

This Indiegogo one-for-one project funds clean drinking water for someone in the developing world every time someone purchases a stainless steel tumbler. The tumblers are insulated and designed to replace paper coffee cups. They're on Indiegogo for the next couple of weeks, and will be working with a group called One Day's Wages to fund clean water projects.
