Cotton Candy Science

Explore the science behind a popular treat!

"Cotton Candy is simply sugar (sucrose) with a little coloring and flavoring added. Sucrose (carbon, oxygen, and hydrogen atoms) is heated by special coils to melting point, which breaks the molecular bonds and converts it to liquefied sugar. The hydrogen and oxygen atoms rearrange to form water molecules which promptly evaporate, leaving only carbon behind. The carbon burns and the sugar begins to caramelize. Basic chemistry! As the sugar caramelizes, its container is spinning at over 3,400 revolutions per second. When the hot liquid sugar meets the cool air outside the machine, thousands of filaments form, creating a delicate and tasty treat. Chemists of all ages will enjoy this fascinating program. It tastes good, too!"
