The Popcorn Machine Of Childhood Is Now Sealed In The Exhibition Hall Editorial Photo

This is a common popcorn machine in childhood. Now it can only be seen in the exhibition hall. Today, the academic name of the so-called `old popcorn machine` is air puffer. In fact, the old popcorn machine makes use of pressure and fire baking to evaporate the water in the corn or rice or millet, liquefy the starch, and open the seal after reaching a certain pressure, then release the air pressure, and the corn or rice or millet will bloom. This is the memory of childhood.
