This simple and elegant device, consisting of a metal pendulum suspended from an executive wooden stand, demonstrates the power of physics. Perfect for the procrastinating professional.
As the pendulum rocks through the fine sand, it gently "writes" an ever changing geometric pattern. The patterns get bigger then smaller then bigger again as the arc of the pendumum also changes.
Create amazing patterns in the sand.
