My Review
One of my pchem profs in college had a pendulum with a mass attached at the end and a spring in the arm of the pendulum. You'd start it swinging like a regular pendulum,then the spring would begin to oscillate. As the amplitude of the spring oscillation increased, the side to side amplitude of the pendulum oscillation would decrease. Then the side to side amplitude would begin to increase and the spring amplitude would decrease. And so on. A really neat, clever toy.
