A consistent call for peace and reflection, this beautiful brass and wood pendulum will fascinate your children. A gentle touch sets it swinging in narrowing circles and ovals. Children and adults will be mystified watching the circles and curved lines become perfect squares and rectangles, and finally one straight line in the sand.
Elementary children will appreciate this concrete demonstration of kinetic and potential energies. Regardless of the lessons inherent, this is a wonderful, peaceful activity for the Montessori classroom.
Cherry finish. Assembled pendulum stands 12½" high; base is 7". Pendulum includes special super-fine sand. Replacement Sand (R261) is also available. Ages 5 and up.
