I have not had cotton candy in a long time. I haven't even been anywhere that sells cotton candy in a long time.

The candy is made by heating and liquefying sugar, and spinning it centrifugally through minute holes—by which the sugar rapidly cools and re-solidifies into fine strands.[2] It is often sold at fairs, circuses, carnivals, and festivals

The last time I was where it was sold it was served on a paper cone or a stick.
Several places claim the origin of cotton candy to a form of spun sugar found in Europe in the 19th century. At that time, spun sugar was an expensive, labor-intensive endeavor and was not generally available to the average person.[7] Others suggest versions of spun sugar originated in Italy as early as the 15th century
Machine-spun cotton candy was invented in 1897 by dentist William Morrison and confectioner John C. Wharton, and first introduced to a wide audience at the 1904 World's Fair as "Fairy Floss"[9] with great success, selling 68,655 boxes at 25¢ (equivalent to $7.2 in 2020) per box.[citation needed] On September 6, 1905, Albert D. Robinson of Lynn, Massachusetts submitted his patent for an Electric Candy-Spinning Machine. The patent was for a combination of an electronic starter, motor-driven rotatable bowl, that maintained heating efficiently. By May 1907 he transferred the rights to the General Electric Company of New York. His patent still remains today as the basic cotton candy machine.
