The magic of the pendulum has been studied for centuries. Start it gently swinging, and watch the path the pendulum takes through the sand, swinging slowly back and forth into beautiful elliptical loops and whorls. Different start angles provide different patterns. Place it on table or desk, and witness the beauty of gravity and momentum at work. Sand included.
Comments about Product: I bought this for my sister who is going through a really tough time right now. I called it her "Peace Pendulum." It's a perfect meaningful gift and can be considered fun or professional or sentimental.
