When the popcorn went into the microwave, it took a while to pop. But radiation was the one that heated the popcorn. The radiation from the microwave vibrates the molecules from the popcorn which in turn heats the kernels up to pop. Radiation is one of the ways that popcorn is made. Another way is by hot air. Hot air is transferred to the kernels and it will make them pop. This process is called convection.
