this idea occured to me while i was at work farting like crazy because of the beer i had drank the night before. so ive noticed that diapers tend to make the smell of a fart last longer, not something u want when u work with the public. a few years back i heard about special underwear with a part that had some kind of charcoal filtering system so it would kill the fart smell and i thought this would be awsome for diapers. im sure this idea is a long ways off but it would be awsome. thoughts or ideas.
