The water trapped within the kernel of the popcorn is the cause of its popping. If the kernel is cooked to a sufficiently high temperature, the water in the kernel will turn into steam. A buildup of pressure inside the kernel occurs as a result of the hard and mainly nonporous shell preventing steam from escaping.

What is the science behind popcorn?

What Causes Popcorn to Pop? The Science Behind It 1 A Closer Examination of the Kernel Corn kernels are made up of two layers. 2 The Optimal Popper. When the kernel is cooked, the little quantity of moisture trapped within the kernel converts to steam, which is pushed over the boiling point by the pressured air inside the kernel during cooking. There are three potential stumbling blocks.

What happens when you pop a piece of popcorn?

This rapid release of pressure inside the kernel results in the expansion of the proteins and starch inside the kernel into a foam that cools and solidifies to form the recognizable popcorn puff. The size of a popped piece of corn is around 20 to 50 times greater than the kernel it came from.
