Now before you start shouting the dangers of the use of food in games, I'd like to say that I've played many games of this sort (under supervision) and everything has gone swimingly. In fact, they're some of my favorite memories from childhood. Lame, I know, but eating food, from a string, without using your hands...
...is just plain old fun. Seriously. You have no idea how entertaining it is until it's your turn to stand under an apple or donut with hands tied behind your back with a bandana, and attempt to get some grasp on taking nibbles at them. Think bobbing for apples, without the mess.
If the weather permits, head outside and tie up enough snacks for your whole group, or stay indoors and tie your strings to a broom and have two adults hold it out limbo style. Don't believe me that it's fun yet. Stop for a second and look up above your head to an imaginary apple on a string and then pretend to bite it. I bet you're giggling at the thought of ten 10 year olds doing it all at the same time!
Other fun snacks on a string can be something with less of a choking hazard, working well for smaller children, such as: cotton candy, marshmallows and popcorn balls. A skewer can be a big help in getting your string or yarn through your food, or simply tie it around if the shape of the food permits.
It's a typically inexpensive way to make everyone laugh and keep everyone occupied at the same time if needs be! Party on!
