Pocket sized UV water purifier
It is called the SteriPen and is promised to purify a glass of water in 90 seconds with the help of ultra violet light. UV light is supposed to kill virii, bacteria and protozoa, including Giardia and Cryptosporidia. UV light has been used to purify water for a long time, but this is supposed to be the first time such a device has been made in pocketable size.
