Popcorn Machine is a tiny electric appliance that heats kernels of popcorn until they pop into an edible form. Heated-air poppers have a fan-like impeller that agitates the kernels in the popping chamber with a turbulent stream of hot air. A heating element in the base generates heat, which is operated by a simple on/off button and controlled by a thermostat. Popcorn Machine has a motor that rotates the fan. The heating element is a resistance coil that looks like a spring.
