A super-mini factory where they make popped corn and rice by traditional method in Korea. Popped corn and rice are sold in front of it as seen. They have two popping machines inside.
Traditional popped corn differs from western popcorn in that the difference between high and low pressure in the closed steel cylinder is used to pop rice or corn. The ingredients under the high air pressure controlled by heat in the tightly closed cylinder are swelled several times immediately with a loud popping sound and heavy smoke just after the cylinder's cap is opened.
I used to stop my ears everytime I had rice popped when I was a child. The appearance and performance of popping machine have been improved and modernized to pop more for a short time.
