In case the washer-and-dryer-safe USB drive just isn't rugged enough for you, this mouse ought to round out your collection of Things You Might Need During an Apocalyptic Event.

The USB Waterproof Mouse, sold by USB Geek, is an optical mouse covered by silicone. Not only does it point, click, and scroll like any other mouse, it is also completely washable, and water and mildew resistant - in case you're surfing the web in a swamp. Also, the site claims that the mouse offers soundless operation, which has the added benefit of allowing you to avoid detection by the alligators while checking your stocks or updating your Facebook page.

But, given the proximity of my coffee mug to my laptop, and my tendency toward clumsiness, I can imagine a few scenarios in which a water-resistant mouse might be useful in everyday life - even if one isn't a professional spy or caught browsing in the rain. And the $17.99 price tag is pretty nice.
