I can't decide on a name.. either the PlopStop or the Flatulencer.
first of all... this is a genius idea! I hate going to someone's house or to a stall and blowing it up for all to hear! I also hate having to pee on the side of the bowl so people won't hear me. you guys know what i'm talking about.
second of all... the plop stopper is a million dollar name just on its own. i love it!
ok, TOTALLY agree here, this idea is perfect, and even before you said "noise cancellation" I was thinking exactly that. Terrific names, too!
hysterical.
