paper straw machine

Principle
It is mainly realized by atmospheric pressure. In the atmospheric environment, when one end of the straw is inserted into the liquid, and the other end sucks out the air or liquid in the straw, the pressure in the tube is reduced to a pressure lower than that of the atmospheric environment, so that the atmospheric pressure outside the straw acts on the liquid outside the tube. surface, push the liquid into the pipette to equilibrate the pressure inside the tube with the air pressure outside the tube.

History
In the 19th century, Americans liked to drink cold light fragrant wine. In order to avoid the heat in the mouth, the freezing strength of the wine was reduced, so they did not drink it directly with their mouths. , its own flavor will also seep into the wine.

At that time, Marvin Stone, a cigarette manufacturer in the United States, got inspiration from cigarettes and made a paper straw. Under the test, it will neither break nor smell strange. Since then, people not only use straws when drinking liqueur, but also use paper straws when drinking other cold beverages.
