A "pipe" is a hollow tube used to transport liquids, gases, or even solids from one place to another. Pipes can be made from various materials, such as metal, plastic, or ceramic, and they come in different sizes and shapes. They are commonly found in plumbing systems, where they carry water to and from homes, as well as in industrial settings for transporting chemicals. In addition to their practical uses, pipes can also refer to a type of smoking device. A smoking pipe typically consists of a bowl for holding tobacco and a stem through which the smoke is inhaled. This form of pipe has a long history and is often associated with relaxation and social gatherings.
