About Space Rotating Dolphin Pendulum

The Newton Pendulum is pleasingly designed with a spherical outer ring along with 3 dolphins placed inside. When you swing the outer circle, it will rotate making the 3 dolphins move too but in a different rhythm. It explains Newton’s Law of Motion. You’ll need 4 AA batteries (not included in the package) or USB cable.
