Fart eating undies
One man has tackled one of the world's most embarrassing body odour issues.
American Buck Wiemer invented a pair of underpants that filters out the smell of farts from the wearer.
The inventor, who won an Ig Nobel prize in 2001 for his unique product, says he designed the underpants for his wife, who as a sufferer of Crohns disease, found herself embarrassed by her inability to control her gassy emissions.
With the underpants made of plastic, the only place for gases to exit the body is through a triangular pocket strategically placed over the bottom. Inside the pocket is a piece of carbon that filters out smelly gases as they pass through, making the wind more palatable to the nose on the other side.
Weimer can't make this year's IgNobel tour but Kees Moeliker, the Dutch biologist who leapt to fame with the first description of homosexual necrophilia in the mallard duck, will be there to report on his latest project.
