I recently had the pleasure of visiting the Science Museum of Minnesota, which houses one of my favorite staircases that I've visited. I have been eagerly waiting to review this staircase ever since I started this blog. I highly recommend visiting this museum solely for this musical experience. So before I give you ratings, let me give you some insight on why this staircase is so special. This staircase plays a b flat scale with each step using a technology known as ADG. This technology is also used in The Science Museum of Boston.
