For years (several decades at least) I’ve made ad hoc double reed “musical instruments” from soda straws.Sometimes I simply pinch one end and then “lip” in a simple tune (or, with particularly unhandy straws, simple one or two notes *heh*), while at other times, I’ll take a pocket knife out and cut a better “reed” to make “better” *heh* music. Here’s a guy who’s taken a similar idea and gone a bit further with it, taking an insulin syringe and engineering a reed for it, etc. Interesting.
