Wrong Direction
Something like an edible Silly Putty smoked tofu and almond serviette (napkin) might almost have merit. Pull edible serviette from separate package glued to side of PepsiCo Crisps With Class. Primly roll over skin of hands to clean them of crisp dust. Ball up and toss into (almost) empty bag. Shake bag to absorb crumbs. Remove serviette from bag and pop into mouth for glorious last bite. Also sold separately in these exciting flavours...
Still noisy, but with the right marketing, that may even be the hook: Show boys how silly they are. Make a show of enjoying the crunch. All the fun of eating crisps without all the mess.
But what do I know? I'm just a software guy.
