The Inexhaustible Bottle is a classic magic trick performed by stage magicians. It dates to the 17th century and has since inspired many variations; well known examples include Any Drink Called For, The Bar Act, Satan's Barman, and Think-a-Drink. During the temperance movement it became The Obliging Tea Kettle, and the modern Magic Tea Kettle remains a common prop available at most magic stores. A slight variation is the Magic Funnel. Today the trick is normally performed for children, although some stand-up shows retain a variation.
