The sensor, naturally, only comes into its own when paired with a mobile app, which asks that you log every component of your meals. Then, once it's sniffed enough of your Paul Blart: Mall Blarts, it'll identify which foodstuffs are causing your most obnoxious guffs and advise you to stop eating them. CH4 is the brainchild of artist and engineer Rodrigo Narciso, and while he assures us that the project is legitimate, this could still be one very long-winded prank. Unfortunately, Narciso's vision of a world where farts are no more doesn't look like it'll arrive any time soon. That's because the Kickstarter to back the gadget has raised less than $2,000 on a goal of $180,000.
