Popcorn is made using three methods in this activity: heat transfer conduction (JiffyPop), convection (air popper), and radiation (microwavable popcorn). When popcorn is exposed to radiation, the kernels absorb the energy and heat up. When water is heated to room temperature, it generates steam, which causes pressure inside the kernel. As the kernel warms, the water expands and creates pressure against the hard starch surface. The hot air pops the kernels and the popcorn is collected in a receptacle. When the kernel is heated, the natural moisture inside turns to steam, and a thick layer of pressure forms inside.
