Why do popcorn kernels pop at different times?

Why do popcorn kernels pop at different times? Now, the answer: The kernels with a higher amount of water in them, when heated, have more steam to expand, and thus reach the ultimate tensile strength of the shell faster. There is also some variability in the tensile strengths of the shells, which lead to some […]
