This is an exhibit which involves the visitor manually. Ball bearings were used to make the freely oscillating pendulum and table . To start the motion ropes are pulled instead of pushing by hand ,this avoids wobbling of the pendulum. An acrylic cover was added to avoid visitor contact. First we used fine grained sand on the table but the markings were not very visible . So finally we settled on white fine stone powder (Rangolipowder)
