The Pendulum Sand Tracer Harmonograph Science Exhibit is a captivating outdoor interactive physics demonstration unit designed for science parks, schools, museums, and STEM learning environments. This large, triangular free-standing exhibit features a wide black inclined surface board mounted on a black powder-coated steel A-frame structure, with a suspended pendulum bob on a thin wire/string that swings freely from the apex tracing mathematical patterns, oscillation paths, and harmonic motion across the surface below.This exhibit brings to life the science of pendulum motion, simple harmonic motion, and Lissajous figures in a visually dramatic and hands-on way.
