If you enjoy traveling abroad, you really need to consider picking up a SteriPen Adverturer ($110). This tiny UV water purifier destroys viruses, bacteria, and cysts, and can purify 32 oz. of water in just 90 seconds. You simply hit the button, put the tip in the water, and stir until the blue light goes off, letting you know it's done. Sure, you can always drink beer, but if you're like us, that'll probably get old by the sixth or seventh day. Don't forget the SteriPen Solar Charger/Case ($43).
