There a number of ways to sterilize your water when you’re camping, traveling, or just feel like making sure. Boiling generally does the trick, but if you don’t have the time to set up the stove, your options can be limited. Nobody likes the taste of iodine, so this UV-based SteriPEN Sidewinder might be a good option.

You crank the handle, it blasts the one-liter bottle with UV, and you can stop when it gives you the all-clear. At $99 it ain’t cheap, but it’s better than getting giardia from some dirty raccoon upstream.
