A funnel is a pipe with a wide mouth, good for feeding, often conical mouth and a narrow stem. It is used to channel liquid or fine-grained substances into containers with a small opening. Without a funnel, spillage would occur.
In culture
The inverted funnel is a symbol of madness. It appears in many Medieval depictions of the mad. For example in Hieronymus Bosch's Ship of Fools and Allegory of Gluttony and Lust.
In popular culture, the Tin Woodman in L. Frank Baum's classic novel The Wonderful Wizard of Oz (and in most dramatizations of it) uses an inverted funnel for a hat, though that is never specifically mentioned in the story—it originated in W.W. Denslow's original illustrations for the book.
In the East Coast of the United States, "beer funnel" is another term for "beer bong". "Funneling" a beer involves pouring an entire beer into a funnel attached to a tube, in which a person then consumes the beer via the tube.
In the computing world, a funnel is frequently used as the icon for the filter functionality.
