Music maker

Cool little music box thingy that we've had for years. It's no more than two inches long, and you turn the little handle, which turns the barrel against a tuned comb, making a nice little plinky tune. On its own you can barely hear it, but when you place it against any flat surface, it resonates and becomes much louder depending what the surface is. One of the best surfaces is a window, which is why we tend to keep this thing lying around on our windowsill. We're easily amused.
