You will find the sugar threads fling against the round outside wall of the machine. And with help of open air these hot sugar threads turns to cool down. There should have an operator to twirl a paper cone around the perimeter. Make sure that the sugar threads sticks each other to the cone. These large piles of spun sugar are known as cotton candy or "Fairy Floss".

The technique of cotton candy making was originally invented nearly in the medieval times. That time the cooking method was called as 'spun sugar'. This cooking system will help to collect some hot syrup on a fork and fling it across the larger container as the sugar melts. As the heated sugar cooled, you have to bundle them together to form a dessert of light threads. In fact, when there is no cotton candy machine people were faced difficult to form sugar threads.

Two candy makers from Tennessee like John C. Wharton and William Morrison accredited with a government grant were invented cotton candy machine in 1897. This electrical machine helps in melting crystallized sugar and a motor to force the threads through a mesh with an electric heating element. In this machine centrifugal force is also applied for grinding sugar through tiny holes.

This cotton candy treat was very expensive at that time which cost was 25 cents a box. For it popularity the cost was increased to 50 cents per box at the admission ticket to the 1904 World's Fair which was very much exorbitant. This new candy treat was a hit to the candy market and its popularity grew up even though the high costs.

Some improvements were taken place on the basic cotton candy machine in around 1949. One of the most reliable Gold Medal Company developed a mechanism for heating and distributing the sugar. This machine helps in eradicating the problems, which were faced in earlier machines. As a result the invent of new cotton candy machines like Cincinnati, Ohio by Gold Medal Company are still used today at fairs, carnivals and charity. Also, there are home versions of the cotton candy machines which are available in the market in recent years with different models.
