How does the cotton candy machine invented?

The cotton candy machine was invented in 1897 by William Morrison, a dentist, and his partner, confectioner John C. Wharton. They created the machine to spin sugar at high speeds, melting it and forcing it through tiny holes to create fine strands of candy. Initially introduced at the 1904 World's Fair, cotton candy quickly gained popularity as a fun and whimsical treat, leading to its widespread commercialization. The machine's design has evolved, but the basic principle of spinning sugar remains the same.
