If the iPhones, massively multiplayer online role-playing games, robot bartenders, and satellite navigation systems hadn’t already tipped you off that we’re living in the sci-fi future predicted quite some time ago, this latest gadget may push you over the edge. It’s a magic wand that you swirl around in water to purify the liquid, according to the New York Times.

If you want to get really technical, the wand’s not actually magic: It uses ultraviolet light to destroy the DNA of various kinds of water-ick like giardia and cryptosporidium. Thus crippled, they can’t reproduce and make you sick. But we like thinking of it as magic.

The wand, called the SteriPen JourneyLCD, costs $129.95 and weighs about 5 ounces, including two disposable batteries.
