That Scarlett Bacon

Seven-year-old Scarlett Bacon has a favorite t-shirt. On the front it says, Today I am going to accomplish something great.
To Scarlett something great means breaking a world record, whether it is trying to make the world's largest pop tart, crush apples with her armpits, or grow the longest fingernails.
Armed with her book, World Records Even a Kid Can Break, and her best friend Clarence, Scarlett is on a mission to break a world record.
Will she do it, or does she accomplish something even more important?
