Hello.

I've been pondering about this for awhile, I'm curious about the inner mechanism of a growler for Teddy bears. What is inside the growler and how can it make the growling noise?
I tried looking this up but couldn't find anything. Anyone knows how it works or has opened one before? Thanks!

A growler is a cylinder with a disk inside it and holes at just one end.  If you tip one holes side down, you will not hear a noise, although you can hear air moving past the disk.  When you tip it back over again the disk falls back down again, and the air squeezing past it rushing out the holes makes the noise.  Depending on the length and width of the cylinder you will get different frequencies - the larger the cylinder the lower it will be.  Hope that makes sense
