The physics of popcorn: Watch the explosion in slow motion

It’s one of the most dramatic transformations in science, and it happens in your microwave. Most popcorn lovers take for granted that a simple kernel of corn can metamorphose into a fluffy treat. But to a pair of French researchers, the popping of corn presents a powerful demonstration of how the laws of physics apply to everything — even a snack food. “This phenomenon contains interesting physics from different fields: thermodynamics, biomechanics and acoustics,” said aeronautical engineer Emmanuel Virot and physicist Alexandre Ponomarenko, the authors of a study published Tuesday in the Journal of the Royal Society Interface. Until now, most research on...
