How to make paper Bags?

Straw, or drinking tube, is a cylindrical, hollow plastic product. Its main function is to drink drinks in cups, but also to suck bone marrow of some cooked animals.

Generally, the diameter is about 0.5 cm, but when it is used to suck yogurt, pearl milk tea and other drinks, the thicker straw will be used, some with a diameter of 1.2 cm. Some are rare, and very small diameter pipettes are used for hot drinks.
