Cotton candy originated in the United States from 65438 to 0987, when it was invented by a dentist named William Morrison and a candy manufacturer named John C. Wharton.

At that time, the candy in Europe was basically drawn, which was brittle, so the dentist invented the cotton candy machine, which used heating and high-speed rotation to make the melted candy wind around the bamboo stick under the action of centrifugal force, and finally formed the cotton candy we saw.

The principle of making cotton candy

Sucrose used to make marshmallows is a granular cubic crystal. The molecules in sucrose crystals are arranged very neatly, and each molecule has a fixed position, just like a neatly parked car in a parking lot.

However, once sucrose enters the cotton candy making machine, its molecular structure will change, and sucrose will become a very long filamentous substance, which will be intertwined like cotton.

The cotton candy making machine is a machine like a big bowl. The center of the machine is a high-temperature heating chamber. Heat breaks the crystal structure and turns sugar into syrup. There are some holes smaller than granular sucrose in the heating chamber. When the sugar rotates at high speed in the heating chamber, the centrifugal motion sprays the syrup from the small hole to the periphery of the "big bowl".
