I came up with this style actually on the way home from an event last week.  It helps solve a few major issues.  It will allow gravity to drain the liquid in it, it is small and compact, and is an all-in-one design.

Doesn’t it look nice?  Parts from 3 separate vendors but it seems to work.

And now on a Jameson bottle.  To make this function, cut a cord to length and attach it to the bottom.  Then attach an airline to the right, and the out tube to the top.
