I got this a long time ago for free in one of my penguin orders. Since then, I've found it in my
magic drawer, and thought about how I could use it.
With a little bit of cleverness, I was
able to use the box as a disappearance of a small coin to add an aural aspect to my close up work.
Oh man, did it work! The sound the box makes is pretty unmistakably "something". When you
open it up and show the box empty, people go "No..."
Neat trick.
