Candy Floss Machine

Typical machines used to make cotton candy include a spinning head enclosing a small "sugar reserve" bowl into which a charge of granulated, colored sugar (or separate sugar and food coloring) is poured. Heaters near the rim of the head melt the sugar, which is squeezed out through tiny holes by centrifugal force.A fringe of liquid sugar, not even really visible to the naked eye in videos of the process, shoots out of the hopper onto the ring. There, it's flung by the force of the spin through the tiny holes, emerging onto the other side as a bunch of nearly invisible threads.
