Cleanup Physicists Reveal the Secrets of Perfect Popcorn, Scale that can measure 0.1-gram increments (optional). Conduction Popcorn Popcorn can be added to kernels. Microwaves work by causing water molecules to vibrate, which in turn produces heat. When popcorn is exposed to radiation, the kernels absorb the energy and begin to vibrate. That's why no popcorn shape is the same, and when you look at the surface through a microscope, (which you can see in the video below), you'll find it's made up of lots of tiny, solidified starch bubbles.

Planting Popcorn. Virot and Ponomarenko explain in their paper, published in the Journal of the Royal Society Interface: "When the popcorn temperature exceeds 100C, its water content (moisture) boils and reaches a thermodynamic equilibrium at the vapour pressure, as in a pressure cooker. The kernel eventually explodes as a result of this pressure buildup. She has taught science courses at the high school, college, and graduate levels. Be carefulyou might need to wait for them to cool before you can count them. Because of this reduced water content, the pressure couldn't build up as high in the preheated kernels, compared to the regular kernels during the popping process, which ultimately leads to smaller kernels. Microwavable popcorn: 3-8 net carbs per cup. Why does it do that? If you use a pan with a glass lid, you'll be able to see when the kernels pop.
