Happy Food Week! We’re excited to bring you a whole week of delicious Moment of Yums leading up to Thanksgiving. Today’s question was sent in by a curious listener who wondered why fluffy, sugary-sweet cotton candy dissolves on your tongue. We asked food scientist Craig Sherwin to help us find the answer.

Got a question that’s cotton you all confused? Send it to us at BrainsOn.org/contact, and we’ll help find a sweet answer for you.
