As a kid, I remember seeing one of these Newton's Cradle piece in the school counselor's office. I loved to play with it and to watch it sway from side to side. Of course, I had to get one for myself. There's just something soothing and relaxing as I hear and watch the balls sway from side to side. I think it's a great conversation piece.. Whether it's on a desk or on a dresser in a room, it'd look perfect. My 8 year old can't stop playing with it either. Love it!
