One Hand Snacking

Another example of markets responding to a need---snacks that you can eat with one hand: [bold added]

Cleanliness-obsessed consumers are fed up with soiled fingers gumming up smartphones, computer mice and other electronica. “I used to eat with my hands and lick my fingers when I was small,“ said Tomoki Yoshino, 19 years old. “But one day, my game controller got all greasy, and it was really gross.” ...

Tokyo snack-maker Koike-ya Inc.,... One Hand brand features a line of splintered potato chips and other snacks that can be consumed like a bottled drink. It’s marketed with a jumbo-size premise—“a new snack style humankind has been waiting for.”

But it's more than the packaging, it's the content, too.

Old-school grease avoider: chopsticks or "chip tongs" (WSJ)

The idea originated with the observation that customers like the mix of potato chip crumbs and flavored powder left at the bottom of the bag. Some eaters tip the chip bag into their mouths to dump the delectable detritus...

The research and development finally cooked up a hand-held package with an angled opening. The company doesn’t release sales figures, but the line has been successful enough to add a “super salt and nori seaweed” flavor. More may be in the works, the company said.

Of course, human ingenuity knows no bounds, and one can devise one's own method of greaseless snacking.

The gentleman pictured on the right can inhale his popcorn without soiling his hands.

The only drawback is that he'll have to wash his hoodie (right?).
