The lady in our local corner shop told me today that when her children was little, she bought one of these types of things.
and filled it up with chocolate covered raisins, M&Ms, raisins, and nuts. Especially almonds, which she was waxing lyrical about how good for you they are. And then she justleft it at child height and whenever they wanted a snack they'd go and help themselves. It was particularly good for snacking in the early morning, when she didn't want to get up and make breakfast yet. The container keeps it all fresh, and the turning handle bit makes it fun, and mixing up the chocolate covered ones with plain ones makes the plain ones more delicious in combination
