iStraw, Personal Water Filtration System

While stumbling around on Stumble! I came across an interesting little straw that claims it can filter out 7 Nines of bacteria from your drinking water, using micro-filtration technology.
Very cool and a must for any traveler, hiker or backpacker. Its easy to carry in your pocket and can mean the difference between a horrible or enjoyable travel experience.
