Gizmag reports the introduction of the second generation Lifestraw, a portable, personal water filtration device for the developing world. Previous sharkride post here. Check out the video below, and consider giving the gift of clean water to those in need this Holiday season. Lifestraws can be purchased through World Outreach for $24.95 - if you buy one, the organization will donate a second one as well, so your contribution has 2x impact.
