Combining Star Trek-like cool factor with the simple practicality of a drug-free way to make dubious water safe to drink, the SteriPEN Classic UV Light Water Purifier destroys viruses, bacteria and cysts with a swizzle of the stick. Since it doesn't use chemicals it's safer for the environment - it doesn't create resistant strains - and it'll make you feel better without your needing more water bottles. $100 USD. [GT]
