How spun sugar became “fairy floss”

The name came from the candy’s appearance. A machine heats sugar until it melts, then spins it through tiny openings. The thin streams cool almost at once into wispy threads, which are gathered into a cloud. To early customers, those delicate strands suggested something finer and more magical than ordinary boiled sweets: fairy floss.

At the 1904 St. Louis World’s Fair, American dentist William Morrison and confectioner John C. Wharton sold the machine-made treat under that name. The fair helped introduce the novelty to a large public, and “fairy floss” became part of its early story.

A name that changed with place

In the United States, “cotton candy” became the familiar name, emphasizing the fluffy mound’s resemblance to cotton. “Fairy floss” did not disappear everywhere: it remains a common term in Australia. Britain generally uses “candy floss.” The same confection, then, carries names shaped by different local images—cotton in one place, a fairy’s delicate thread in another.

The original phrase captures the trick that made the sweet memorable: a handful of ordinary sugar transformed into something that looks almost weightless.
