I posted the other day about this mechanical tin bank that comes to us by way of mechanical master, Falk Keuten of the Spiel und Kunst mit Mechanik blog. He decide to reshoot the video to show the mechanism better. It worked. Thanks Falk!

If you like this kind of thing in general, here's a list of posts on mechanical banks that I've done over the years. It could keep you busy for a few minutes.
