It's a nice trick. Well made with a foolproof and well-hidden method. May take you a couple of minutes to get the hang of it, but it's easy enough. Gets a good reaction. The only downside is that the coloured paper circles stuck on the brass discs can get a bit tatty. I suggest removing the paper and painting the discs with enamel paint (for example, Humbrol). Also blunt the end of the short rod you poke through the hole: it stops it from scratching the paint (or paper circles). I think it's something you'd use regularly.
