The term "funnel-shaped" describes an object or structure that is wide at one end and gradually narrows down to a smaller opening at the other end. This shape resembles a funnel used in cooking, which helps pour liquids into containers without spilling. Funnel shapes are commonly found in nature and various man-made items, such as funnels, tornadoes, and certain flowers. In engineering and design, funnel shapes can be utilized to direct flow, whether it be air, liquids, or even crowds of people. For example, a funnel can help channel water efficiently, while a funnel-shaped structure in architecture may enhance acoustics in a concert hall.
