Classic footage from Moon - Hammer vs Feather

A classic experiment, done by Apollo astronauts on the moon, proved that, minus air friction, even a feather has the same acceleration due to gravity as heavier objects, such as a hammer. You can even notice that the acceleration is less than on earth by watching the fall. The acceleration of gravity on the moon is about 1/6 the earth's value of 9.8 m/s^2, which puts it at about 1.6 m/s^2.
