Every day we get new evidence that physicists are just like us: hungry. Physicist Frank Crawford noticed a strange, musical effect when he stirred a packet of hot chocolate mix into his water. Find out about the physics he discovered behind this odd, shifting sound.
There is an astounding amount of physics centering on breakfast. The Butter Side Down Effect covers toast. The Brazil Nut Effect takes a look at breakfast cereal. The Cheerio Effect looks at . . . a different kind of cereal. The Coffee Ring effect takes into account the nation's drug of choice. And in 1982, the American Journal of Physics published the work of Frank Crawford. He had turned his attention to instant hot chocolate, and what happened when it was mixed into water.
