The iStraw from ThinkGeek is essentially “a polycarbonate straw fitted with a special membrane, which uses micro-filtration technology to clean your water rather than expensive and bad tasting water cleaning tablets.” Click here for first picture in gallery.

It reduces up to 99.99999% of all waterborne bacteria, including Giardia and Cryptosporidium. When used properly, the iStraw is capable of filtering up to 500 litres of water.
