Product Information

Trickle sand from a metal canister hung from a swinging, compound pendulum and create interesting patterns called Lissajous Figures, named for the French mathematician who was the first to study these kind of patterns. Changing the proportional length of the string varies the pattern and allows discussion of harmonic relationships in nature.

You can experiment with the position of the slider to set up differing patterns, whereyou can find certain ratios to get predictable patterns.
