Sand pendulums are an easy and beautiful method for students of all ages to learn a bit about the harmonic motion. These devices are easy to build and can be adjusted to give a variety of patterns. A pendulum that begins with two point of support can alter the periods of the pendulum as it moves on two perpendicular axis at the same time. The video gives simple instructions on the materials needed and how to adjust the configuration to vary the design.
