It turns out that watching movies is an entertainment activity from abroad. In the early days, you wouldn't eat popcorn when watching movies, because the previous movies were silent movies, and only the educated people in the upper class enjoyed the right to watch movies. In this case, the viewing environment must have certain requirements.

Snacks such as popcorn are easy to stain the carpet, followed by worrying that the sound of eating popcorn will affect the viewing effect. By 1927, the film entered the sound age, and the requirements for the audience were relaxed. As long as they have money to buy tickets, they can go in and out of the cinema. Especially in the 1930s, the United States relied on the low cost and mass production of popcorn.

Popcorn is a kind of puffed food made by putting corn, ghee and sugar into a popcorn machine. It tastes sweet. Put a proper amount of corn into the popcorn pot, seal the top cover, then put the popcorn pot on the stove and keep rotating to make it evenly heated, and then the popcorn can pop out.
