How do you make candy floss sugar?

You can't make candy floss sugar. It's not a separate type of sugar. Candy floss (or cotton candy) is made using granulated sugar and a special machine that spins the sugar into thin strands.

The process involves heating the sugar until it melts, then forcing it through a spinning head with tiny holes. The centrifugal force of the spinning head creates the thin, wispy strands that form the candy floss.

So, you don't need to make a special type of sugar for candy floss. You just need regular granulated sugar and a candy floss machine!
