Some things, though, that get their "flavors" ONLY from their smells, like oils, are truly flavorless with the clips. Finally flavorless oils for the supertasters. And any other "food" that doesn't register through the tastebuds (no salty, sweet, etc) will also be truly tasteless. No clue what these might be other than our oils.
Anyone tried extra virgin oils of various sorts, nose-clipped, to see if you can taste them or not? (Thus far I've only used my refined coconut oil, with great success.) Remember to leave the clip on a good 5-10 minutes after taking the oil, and get a lot of rinsing or drinking water done before you take them off.
Seth, another marketable product for you. A noseclip range. You can team up with some of the gang from Project Runway to design a whole line. Ideas, for a start:
-The Speedo: sleek, minimalist, easy on, easy off
-The Birkensmell: leather (or
faux), ultra-comfortable, and obligingly homely
-The Natural: flesh toned in the hues of humanity: "You can't even see it's there!"
-The Clown: Well, this should be obvious. If you're going to use a clip, might as well make it fun
-The Pixie: some little pixie/sprite thing clamping the s*** out of your nose
-The Groucho: comes with entire fake nose, eyeglasses, and mustache (but a small one, so it doesn't drag through your food)
-The Warhol: pop-culture art noseclips, in a variety of colors. Can even have a little Marilyn at the end.
-The Snooty / The Monty Python: a miniature hand using thumb and finger to pinch the nose
-The Silver Clothespin: for the privileged.
"She was born with a silver clothespin on her nose"....
-Temporary nose jewellry: try to pass it off as a decoration while you eat... (I can hardly type these at this point; I think I'll give up before I fall off my chair.)

Haha. But seriously, I'd buy a speedo/Birkensmell version.

And maybe a clown...
