FUNNEL, 'B.G.', 75mm

A funnel is a tube or pipe with a broad aperture at the top and a narrow opening at the bottom that is used to guide liquid or powder into a tiny hole. Stainless steel, aluminium, glass, or plastic are the most common materials used to make funnels. The substance used in its manufacturing should be strong enough to support the weight of the substance being conveyed and should not react with it.
