The straw, or drinking straw, is a cylindrical, hollow product. Its main function is to drink the beverage in the cup, and it is also used to suck the bone marrow of some cooked animals.
Generally, the diameter is about 0.5cm, but when used to drink yogurt, bubble tea and other drinks, a thicker straw is used, such as 1.2cm. Some are less common, straws with very small diameters are used for hot drinks.
Straws have always been made of plastic, but in recent years they have gradually been banned due to plastic pollution.
