The idea that a dentist invented cotton candy is a popular myth. The true inventor of cotton candy is generally agreed to be William Morrison and John C. Wharton, who created a machine that could spin sugar into a fluffy confection at the 1904 World's Fair in St. Louis, Missouri.
Despite the myth, cotton candy remains a popular treat enjoyed by people of all ages. It is often associated with carnivals, fairs, and other festive events. Cotton candy is also a popular topping for ice cream and other desserts.
