They're the BEST for roasting marshmallows on an open fire! If you're feeling kind, you just let the sugar on the outside melt for a candy shell, and if not, you can watch the poor chicks deform and melt >:] They're also fun to put in the microwave because they expand so much. Just make sure to eat them quickly once they're huge! They get really gross when they collapse.
On their own I don't like them, but they're great in s'mores.
