SANDPENDEL

By using earth rotation inertia, the pendulum, equipped with a steel tip, draws in the fine sand a circular drawing of a striking regularity.
Pendulum reminds us that Léon Foucault-French physician of the 19th century-used it to demonstrate the inertia caused by the earth rotation movement.
Its slow and regular movement may be fixed during long minutes, and provides a great relaxation.
