I come from a family of snackers. Granola? Popcorn? Nuts? You name it, we're probably eating it. Yes, right this very minute.
But there's one member of my family (cough, Dad, cough) who tends to consume said snacks in a peculiar fashion. Let's use mixed nuts as an example.

My dad will take a handful of nuts, then shake them in his hand as though he's about to roll some dice at the casino.
