First, we draw a trapezoid with a straight line, big and small; Continue to draw a trapezoid with a straight line; Then we draw a wavy line and outline the outline of a popcorn; Draw other popcorn and outline the overall outline according to the practice in step 3; Then draw the stripes on the popcorn box into a straight line and decorate it; Finally, just fill in your favorite color.

Popcorn introduction:

It is a kind of puffed food made by putting corn, ghee and sugar into a popcorn machine, which is very sweet to eat. Put a proper amount of corn into the popcorn pot, seal the top cover, and then put the popcorn pot on the stove and keep rotating to make it heated evenly, and then pop the popcorn. Thousands of years ago, popcorn was first discovered in the Inca Empire and is one of the oldest snacks in the world.

The principle of popcorn:

Put a proper amount of corn (or rice) into the popcorn pot, seal the lid, and then put the popcorn pot on the stove and rotate it constantly to make it evenly heated, so as to make delicious popcorn.

This is because in the process of heating, the temperature in the pot keeps rising and the pressure of the gas in the pot keeps increasing. When the temperature rises to a certain extent, the rice grains will gradually soften and most of the water in the rice grains will turn into steam. Because of the high temperature, the pressure of water vapor is great, which makes the softened rice grains expand.

But at this time, the pressure inside and outside the rice grain is balanced, so the rice grain will not explode in the pot. When the pressure in the pot rises to 4-5 atmospheres, the top cover of the popcorn pot suddenly opens, the gas in the pot expands rapidly, and the pressure drops rapidly, which increases the pressure difference between the inside and outside of the rice grains, resulting in the rapid expansion of high-pressure steam in the rice grains, which instantly explodes the rice grains into popcorn.

Popcorn is mainly divided into traditional popcorn and new popcorn:

Traditional popcorn is made by heating corn in a small converter at high temperature. Some saccharin may be added to taste, but margarine fat will not be added. Although the fat content of traditional popcorn is not high, the traditional small converter may release lead at high temperature.

The food counters in cinemas are all baked with electric appliances. Modern production technology reduces the risk of lead harm to human body, so there is no need to worry about its lead pollution. However, there are too many additives in modern popcorn, and a lot of margarine, essence and pigment are often added in the production process, which increases the energy and trans fatty acid content of popcorn, thus increasing the risk of cardiovascular and cerebrovascular diseases and zinc deficiency after eating.
