The SteriPen Sidewinder may be the healthiest hand job you ever perform. This water purifier uses a simple hand crank to destroy harmful bacteria and germs.

The SteriPen Sidewinder is a battery-free purifier, which makes it great for residents of developing nations as well as outdoorsy men and women. The SteriPen Sidewinder can purify a lot of water at an incredibly fast speed, I'm talking one liter in 90 seconds. This purifier will be available in September for $99. I can hardly wait.
