Drinks Whistle

Now that plastic straws are thankfully largely a thing of the past, several alternatives have taken their place. One alternative is a sort of telescopic metal tube that comes complete with a wire brush to clean it after use, all carried around in a special container.

This seems like an elaborate arrangement for such a basic task, so I have decided to add another function to the straw to more fully justify its existence. The extra function here is that of a tin whistle.

In order to use your metal straw as a whistle, you grip it at one end then twist it a half rotation in an anticlockwise direction. This action reveals a set of finger holes along one side that were previously covered by the protective water-tight rotating sleeve arrangement. You then screw on the reed end that comes in the container and you're all set to begin playing your diminutive tin whistle.

The tin whistle is a very basic musical device at the best of times, but being extremely narrow results in the generation of a distinctive sound unique to the instrument. Restaurants are encouraged to provide free drinks for those who's playing is adept enough to entertain the other customers (on request).
