I was on nytimes.com today and watched a little video about this new tool for water purification. It looks really cool. You can use it to drink through, like a large straw that gets rid of a lot of the impurities...they show people using it in a puddle of water in countries that have been hard hit by natural disasters or do not have clean water. It's really cool. Just thought i'd share.

to go NYtimes.com and it's one of the displyed videos about 1/2 way down the page.
