(CNN) -- Is your head spinning? December 7 is National Cotton Candy Day!
It seems unlikely, but two dentists can be credited with giving us the cotton candy we know today. The first, William Morrison, developed a machine that could spin sugar in 1897. Along with John Wharton (a confectioner), he introduced the world to the machine-made version of an already popular product at the St. Louis World's Fair in 1904.
At the time, cotton candy was expensive to make and cost a lot to purchase, making it unavailable to the average Joe.
The second was a Louisiana man called Joseph Lascuax. He patented a similar machine in 1921, calling his product cotton candy. Cotton candy had previously been called candy floss or fairy floss in other parts of the world.
These days cotton candy machines are relatively cheap to buy. You can also MacGyver your own using a bottle cap.
You will need special sugar if you want to make the colorful confection at home -- regular granulated sugar won't melt properly. Essentially a cotton candy machine heats the sugar until it melts and solidifies in the air as it spins around a bowl.
