Latex Glove Bagpipes

A how-to video:

I dated a girl many years ago who was fascinated by music theory. At dinner one time, while we were chatting, she took out a small pocket knife and made a playable recorder with the straw in her drink. I don't remember the tune she played on it, and yeah the sound quality was what you would expect, but it was a recognizable tune. She made other impromptu instruments at times as well and even got me playing an instrument for a while.
