How does the air in a air popper get so hot?

In an air popper, hot air is generated by a heating element that rapidly warms the air as it passes over it. This heated air is then circulated at high speed through the popping chamber, where it evenly heats the popcorn kernels. As the temperature rises, the moisture inside the kernels turns to steam, building pressure until they pop. The efficient airflow and direct heating enable the air popper to reach the necessary temperatures for popping quickly.
