Machine spun cotton candy was invented by a dentist in 1897. Before that time, it was expensive and labor-intensive. Dentist William Morrison and confectioner John Wharton introduced it at the 1904 World’s Fair. They called it Fairy Floss.
Later in 1921, dentist Joseph Lascaux invented a similar cotton candy machine. He patented this machine as the Cotton Candy machine.
This day pays tribute to cotton candy (and fairy floss).
