Popcorn is a variety of corn kernel which expands and puffs up when heated; the same names also refer to the foodstuff produced by the expansion. A popcorn kernel’s strong hull contains the seed’s hard, starchy shell endosperm with 14–20% moisture, which turns to steam as the kernel is heated.

Cotton candy, also known as fairy floss and candy floss, is a spun sugar confection that resembles cotton. It usually contains small amounts of flavoring or food coloring.
