I think marshmallows are technically mostly sugar. Maybe someone will wiki them and give a link. I am too lazy.

There is a variation of roasted marshmallows called s'mores. You place the roasted marshmallow between two graham crackers along with a piece of a hersey chocalate bar (thin milk chocolate bar) the hot gooey marshmallow melts the chocolate and softens the graham cracker. Makes a delious treat that a 10 year can take pride in creating.

by the time one reaches adulthood that much sugar is revolting to most, but as a 10 year old, any sugar rush is great fun.
